Change Employer After H1B Lottery Selection

Can you change employer after H1B lottery selection but before October 1? Usually, no. A selected H-1B registration belongs to the employer that submitted it. A new employer cannot take over that selection, file its own cap petition using that selection, or rely on H-1B portability before your H-1B status has started. The safest path is usually to have the selected employer file and maintain the cap petition through the October 1 effective date, then consider a change of employer after you are in valid H-1B status.

This issue comes up often for F-1 students on OPT or STEM OPT who receive a better offer after the lottery, employees whose sponsoring employer delays the petition, and candidates whose original offer is rescinded before October 1. The legal answer turns on one question: are you already in H-1B status, or do you only have a lottery selection and future H-1B start date?

Practical rule: Lottery selection is permission for the selected employer to file a cap-subject H-1B petition. It is not portable work authorization, and it is not a cap number that you can carry to a new employer before H-1B status starts.

Can you switch jobs after H-1B lottery selection?

If only the registration has been selected, the new employer cannot file the cap petition based on that selection. The petitioner named in the selected registration must file Form I-129 during the filing window stated on the selection notice. USCIS said in its FY 2027 registration notice that the initial registration period ran from March 4 to March 19, 2026, with selection notices expected by March 31, 2026, and a $215 registration fee for each registration, in the USCIS FY 2027 H-1B cap announcement.

The annual H-1B cap remains 65,000 regular cap numbers plus 20,000 additional numbers for beneficiaries with qualifying U.S. advanced degrees. DHS confirmed those cap figures when it announced the FY 2027 weighted selection system on February 27, 2026, in the DHS H-1B selection process notice. Selection gives the named employer a filing chance. It does not give the worker an employer-neutral H-1B approval.

Here is the decision tree most candidates should use:

• Selected registration only: You cannot move that selection to a new employer. The original petitioner must file, or the selection is unused.
• Cap petition filed but still pending before October 1: A different employer generally cannot file a transfer based on the pending future H-1B. If the original petition is withdrawn before it becomes effective, you risk losing the cap number.
• Cap petition approved for change of status with October 1 start date: Before October 1, you usually remain in your prior status, such as F-1 OPT. H-1B portability generally does not apply yet.
• October 1 has arrived and you are in H-1B status: A new employer may be able to file an H-1B change of employer petition, and portability may allow work after filing if the legal requirements are met.
• Consular notification approval: You are not in H-1B status until you are admitted to the United States in H-1B status. Do not assume portability applies before that admission.

If you are still comparing sponsors, use job postings from employers with a real filing history. Avisa tracks employers that sponsor visas, including companies with H-1B activity across technology, finance, health care, consulting, universities, and research organizations.

Why does the lottery selection belong to one employer?

The H-1B cap registration system is employer-specific. The employer registers a named beneficiary for a specific intended job, work location, wage level, and occupational classification. USCIS then selects eligible registrations, not free-floating workers.

USCIS explained this employer-specific structure in its December 19, 2024 Small Entity Compliance Guide, Improving the H-1B Registration Selection Process and Program Integrity. That guide states that the petition must be based on a valid selected registration and warns that changes in the registration information, including the employer, wage level, SOC code, and area of intended employment, may create denial or revocation risk.

That structure matters because a new employer is a new petitioner. Even if the new role is similar, for example a Software Engineer role at Meta instead of a Software Engineer role at Amazon, the selected registration did not list the new employer. The new employer must have its own selected registration for that fiscal year unless another rule applies, such as a cap-exempt petition.

Common job-search wording creates confusion. Recruiters may say they can “transfer your H-1B” after you are selected. That phrase is correct only after you have H-1B status or have a prior cap-counted H-1B that can be used in a later petition. Before October 1, many selected F-1 students have an approved future H-1B change of status, but they are still in F-1 status until the effective date.

What happens between selection and October 1?

The H-1B timeline creates a long gap between March selection and the usual October 1 start date. During that gap, your immigration position can change several times. Each step has a different job-change rule.

Step 1. Registration selection

The employer receives a selection notice in its USCIS online account. The notice lists a filing window. For FY 2027, USCIS announced that the registration period would open March 4, 2026 and close March 19, 2026, with selection notices by March 31, 2026, in the USCIS FY 2027 registration announcement.

At this stage, you have no H-1B status from the selection. If you are an F-1 student on post-completion OPT, your work authorization still comes from your EAD and F-1 status rules. If you are on STEM OPT, you must keep the I-983 training plan, employer reporting, and address reporting accurate. A job move during STEM OPT also triggers STEM OPT reporting duties, which Avisa covers in STEM OPT reporting requirements and deadlines.

Step 2. Cap-subject Form I-129 filing

The selected employer files Form I-129 with the H supplement, a certified Labor Condition Application, filing fees, company support documents, and evidence that the job is a specialty occupation. A startup filing for a Product Manager role at $115,000 in San Francisco and a hospital filing for a Clinical Data Analyst at $82,000 in Boston both must file through the employer named in the selected registration.

If you receive a competing offer before the I-129 is filed, the new employer cannot simply replace the petitioner on the selected case. The original employer can file its own petition if it still intends to employ you. The new employer can hire you under your existing nonimmigrant work permission if you have it, such as OPT or STEM OPT, but that is separate from using the selected H-1B registration.

Step 3. Petition approval before the start date

Approval before October 1 does not always mean you can change H-1B employers immediately. If the case was filed as a change of status from F-1 to H-1B with an October 1 start date, your H-1B status starts on October 1 if the change of status takes effect and you maintained the underlying status through the change. Until then, you usually remain in F-1 status.

The February 2, 2024 H-1B Registration Final Rule removed the old regulatory limit that restricted requested start dates to October 1 for some cap cases. The Federal Register notice states that DHS removed language at 8 CFR 214.2(h)(8)(iii)(A)(4) that had restricted requested start dates, allowing certain petitions to request start dates after October 1, in the Federal Register H-1B Registration Final Rule published February 2, 2024. Later start date flexibility helps some employers plan onboarding, but it does not let a different employer use the selected registration.

Step 4. October 1 and H-1B activation

For a change of status approval with an October 1 start date, October 1 is the usual point at which H-1B status begins. If the petition remains valid, you maintained your prior status, and the job still exists, the H-1B becomes active. After that, an H-1B change of employer petition may become possible.

If the sponsoring employer withdraws the petition before October 1, or if the job offer disappears before the change of status takes effect, the case can fail to produce usable H-1B status. That is the risk many candidates underestimate. A selected registration plus an approval notice is weaker than an active H-1B job after the effective date.

Does H-1B portability apply before October 1?

H-1B portability allows certain H-1B workers to begin employment with a new H-1B employer after the new employer files a nonfrivolous Form I-129 change of employer petition, rather than waiting for approval. The rule is powerful, but it has a threshold requirement: the worker must already be in H-1B status or otherwise meet the statutory portability conditions.

USCIS describes portability in its worker options guidance, stating that an H-1B worker may begin working for a new employer as soon as the new employer properly files a nonfrivolous H-1B petition, in the USCIS options for nonimmigrant workers guidance. That guidance is aimed at people who are already H-1B workers, including workers affected by termination.

A March lottery selection does not make an F-1 student an H-1B worker. A July approval notice with an October 1 change of status date usually does not make that student an H-1B worker in July. The worker remains in F-1 status until the change of status date, assuming the change takes effect. That is why portability usually cannot solve a pre-October job switch.

Avisa has a separate guide on standard H-1B transfers after status begins. If you have already passed the effective date or you have been in H-1B status before, read H-1B transfer rules for changing employers safely before resigning or starting new work.

What are the common pre-October job-change scenarios?

The right answer depends on the status of the cap petition and the candidate’s current work authorization. These examples show how the same rule produces different results.

Scenario 1. You are selected in March and get a better offer in April

Assume your current employer, a consulting company in Dallas, registered you for a Business Systems Analyst role at $88,000. In April, a bank in New York offers you a Data Analyst role at $125,000. The bank asks whether it can file your H-1B petition using your selected registration.

The answer is no. The selected registration names the Dallas employer. The New York bank may hire you on OPT or STEM OPT if you have valid authorization and the role qualifies under F-1 rules, but it cannot use the Dallas company’s cap selection. If the Dallas company does not file the cap petition, that selection will not turn into an H-1B approval.

Scenario 2. The original employer filed the petition, and it is pending in August

Assume a software company filed your cap petition in June for an October 1 change of status. In August, a health-tech company offers you a Machine Learning Engineer role. The pending petition does not give the health-tech company a transfer option before October 1.

If you accept the new role and the original employer withdraws the pending petition, you may lose the cap case. If you keep working for the original employer through October 1 and the petition is approved and active, a later transfer may be possible. Candidates sometimes try to negotiate a delayed start with the new employer so the H-1B can activate first.

Scenario 3. The cap petition is approved in July, but you want to resign in September

This is one of the riskiest situations. An approval notice for future H-1B status is not the same as active H-1B status. If you resign before October 1 and the employer withdraws the petition, the change of status may never take effect. You may remain in F-1 or another prior status if you have maintained it, but you may not become cap-counted through that case.

Some candidates plan to resign on October 2 and have the new employer file a transfer. Even then, details matter. The new employer must prepare a certified Labor Condition Application, file a complete I-129 package, and choose whether to request premium processing. Your original H-1B job should be real on October 1, and you should avoid any gap or unauthorized work.

Scenario 4. The employer rescinds the offer before October 1

If the sponsoring employer rescinds the job before the start date, the petition may be withdrawn or revoked. You should immediately identify your current status, your work authorization end date, and whether you have unemployment days left if you are on OPT. F-1 students should review how to maintain valid F-1 status while job searching, because a failed H-1B change of status does not excuse OPT unemployment rules or SEVIS reporting duties.

A new cap-subject employer usually cannot rescue the same year’s H-1B selection unless it also has its own selected registration for you. A cap-exempt employer may be a separate option, discussed below.

Scenario 5. You have consular processing approval instead of change of status

With consular notification, USCIS approves the petition but does not change your status inside the United States. You must obtain an H-1B visa stamp if required and be admitted in H-1B status. Until admission in H-1B status, you are not working in H-1B status for that employer.

Consular cases can be more flexible for travel planning, but they do not turn a pre-October job offer into a portable H-1B transfer. If your case involves travel, status change, or stamping questions, compare the mechanics in H-1B consular processing versus change of status.

What happens if the original employer withdraws before October 1?

A withdrawal before the H-1B start date can destroy the practical value of the selection. If the cap-subject petition was never filed, there is no H-1B case. If the petition was filed and later withdrawn before approval, USCIS will usually stop the case. If the petition was approved for future change of status and then withdrawn before the effective date, the change of status may not activate.

The hardest cases involve a candidate who has an approval notice but never starts the H-1B job. The candidate may believe they have been “counted against the cap,” while the next employer may believe it can file a transfer. That may be wrong if the first approval never became effective or was withdrawn before the start date. There is no final DHS rule from the last 12 months that created a safe pre-October transfer right for selected beneficiaries.

Ask the original employer or its attorney for the exact case status before making decisions. You want to know:

• Was Form I-129 filed?
• Was it filed as change of status or consular notification?
• Was it approved, denied, withdrawn, or still pending?
• What start date appears on the approval notice?
• Has the employer sent a withdrawal request to USCIS?
• Will the job and payroll be available on the H-1B start date?

Do not rely on a screenshot of the lottery selection alone. Selection is a filing opportunity. It is not proof that an H-1B petition was filed or approved.

What can a new employer do before October 1?

A new employer still has options, but most do not involve taking over the selected cap case. The right path depends on your current visa status, work authorization, education, role, and employer type.

Hire you under existing OPT or STEM OPT work authorization

If you are on OPT, the new job must relate to your field of study, and you must track unemployment days. If you are on STEM OPT, the employer must meet STEM OPT employer requirements, complete a Form I-983 training plan, and use E-Verify. For detailed employer obligations, read STEM OPT employer requirements.

This option can help a candidate move jobs before October 1, but it does not preserve the selected H-1B cap number with the new employer. If the original cap case fails, the new employer may need to register you in a future H-1B cycle or use another visa category.

Wait until H-1B status becomes active, then file a change of employer petition

This is often the cleanest immigration strategy if the original job remains available through the start date. The candidate stays with the sponsoring employer until H-1B activation, then the new employer files an H-1B change of employer petition after the candidate is in H-1B status.

The business challenge is timing. A new employer may not want to wait until October or later. Candidates can explain that starting too early may void the H-1B path and create unauthorized work risk. Serious visa-sponsoring employers usually understand that a delayed start is safer than a failed transfer.

Use a cap-exempt H-1B employer

Universities, certain nonprofit entities related to or affiliated with universities, nonprofit research organizations, and government research organizations may file cap-exempt H-1B petitions outside the lottery. If your new offer is from a cap-exempt employer, the employer may not need your cap selection at all.

Examples include a university research lab hiring a Data Scientist, a teaching hospital hiring a Bioinformatics Analyst, or a qualifying nonprofit research institute hiring an AI Research Engineer. The analysis is employer-specific, not just job-title-specific. A private vendor working near a university does not automatically become cap-exempt.

Consider another visa category if you qualify

Some candidates have alternatives. Canadians and Mexicans in qualifying professions may look at TN status. Australians may consider E-3. Chilean and Singaporean citizens may consider H-1B1. People with strong publication, judging, press, funding, or leadership evidence may consider O-1. These routes have separate rules and do not depend on transferring the selected H-1B registration.

For candidates with long-term U.S. plans, a green card strategy may also matter. H-1B is a dual intent category, but F-1 is not. If you are planning PERM or EB-2 NIW, get advice before taking steps that affect status, travel, or immigrant intent.

Which 2026 rule changes affect this decision?

Several 2026 H-1B changes and proposals created noise around employer changes, but none created a new right to transfer a selected registration before October 1.

Weighted H-1B selection for FY 2027

DHS announced on February 27, 2026 that it finalized a weighted selection process for FY 2027 H-1B registrations to prioritize higher-paid, higher-skilled beneficiaries, replacing the purely random selection system, in the DHS weighted selection announcement. That change affects selection odds and employer registration strategy. It does not make the selection transferable to a different employer.

Start date flexibility from the 2024 final rule

The February 2, 2024 Federal Register final rule removed the old October 1 start date restriction in 8 CFR 214.2(h)(8)(iii)(A)(4) for certain cap petitions. This allows some petitions to request start dates after October 1. A later start date can be useful if an employee’s OPT runs longer or an employer has a later project start, but it may also delay the point at which H-1B status becomes active. A later start date can delay transfer timing if portability depends on active H-1B status.

9-11 Response and Biometric Entry-Exit Fee

DHS issued a final rule on August 10, 2026, effective September 9, 2026, expanding the statutory 9-11 Response and Biometric Entry-Exit Fee to cover all H-1B and L-1 petitions filed by covered employers, including extension-of-stay petitions and change-of-employer filings. The archived USCIS H-1B page describes the rule on a page captured at USCIS H-1B specialty occupations. CB Immigration reported the fee amounts as $4,000 for H-1B petitions and $4,500 for L-1 petitions in its New I-129 Edition and 9-11 Biometric Fee update.

This fee issue matters for hiring budgets. A covered employer considering a post-October H-1B change of employer petition may face a higher cost. It still does not let that employer file a pre-October transfer for someone who is only lottery-selected.

Proposed $103,265 cap-subject fee

DHS proposed on August 24, 2026 a one-time $103,265 fee for cap-subject H-1B petitions, including advanced-degree exemption petitions, in the DHS proposed additional H-1B fee notice. DHS estimated about 85,000 cap-subject petitions annually and about $8.8 billion in revenue if the proposal were finalized.

As of October 29, 2026, that fee remained a proposal, not a final rule. Employers should budget based on current filing rules while tracking the proposal. Candidates should not let a recruiter claim that the proposed fee has already ended all H-1B transfers or cap filings.

The $100,000 fee court decision

Axios reported on June 8, 2026 that a federal judge struck down the $100,000 H-1B fee imposed by a September 2025 Presidential Proclamation, in its report on the H-1B fee ruling. That decision addressed the proclamation fee. It did not create a pre-October employer-change right for selected beneficiaries.

Which misconceptions cause the most damage?

Pre-October H-1B job changes are risky because candidates often hear short answers from recruiters, friends, or managers. These claims need closer review.

Misconception 1. “I was selected, so I own the lottery slot.”

You are the beneficiary of a selected registration. The employer is the petitioner. The petition must be tied to the selected employer and job information. USCIS can deny or revoke petitions where the filing does not match the registration or where the registration was not valid for the offered job.

Misconception 2. “An approved petition can always be transferred before October 1.”

An approval with a future start date may still leave you in your old status until that date. Portability usually depends on H-1B status or prior cap-counted H-1B eligibility. If the first petition is withdrawn before the start date, the new employer may have no valid H-1B basis to use.

Misconception 3. “Premium processing fixes the timing problem.”

Premium processing can speed USCIS action on a petition, but it does not change the cap registration owner. It does not make F-1 status into H-1B status before the effective date. It may help a new employer after October 1 if a transfer is otherwise allowed.

Misconception 4. “A similar job title means the new employer can file.”

USCIS looks at the petitioner, offered role, worksite, wage, SOC code, and supporting evidence. A Software Developer role at Google and a Software Developer role at a 20-person fintech startup may use similar duties, but they are different petitioners and different job offers.

Misconception 5. “The 2026 fee changes changed portability.”

The weighted lottery, the 9-11 fee rule, and the proposed $103,265 cap-subject fee affect selection and cost. They do not replace the basic rule that pre-October lottery selection is employer-specific.

What should candidates do before accepting a new offer?

Before accepting a new offer between selection and October 1, collect documents and ask direct questions. Immigration timing should be part of offer negotiation, not an afterthought after resignation.

1. Ask the original employer whether the H-1B petition has been filed. Get the receipt number if available.
2. Confirm the filing type. Change of status and consular notification create different risks.
3. Ask whether the employer will keep the petition active through the start date. Some employers withdraw immediately after resignation.
4. Check your current work authorization. F-1 OPT, STEM OPT, H-4 EAD, L-2S, or another status may control whether you can start the new job now.
5. Ask the new employer’s immigration counsel for a written timing plan. The plan should state whether they will wait for October 1, file after activation, use cap-exempt H-1B, or use another visa.
6. Do not start unauthorized work. A high salary does not fix status violations.
7. Keep SEVIS and address records current if you are in F-1 status. H-1B approval for the future does not erase F-1 reporting rules before the change.

If you are still on OPT and your H-1B plan is uncertain, review your OPT timing carefully. Avisa explains cap-gap and status planning in OPT to H-1B transition timing.

What should the new employer ask before making the offer?

Hiring teams should avoid telling candidates that every selected H-1B can be transferred. A wrong promise can cause a failed hire, a withdrawal fight with the first employer, and a candidate status problem.

A practical intake should ask:

• What is your current immigration status?
• Do you have current work authorization independent of H-1B?
• Who submitted the selected registration?
• Has the cap petition been filed or approved?
• Is the approval change of status or consular notification?
• What start date appears on the petition or approval notice?
• Will your current employer withdraw if you resign?
• Have you ever held H-1B status before?

The employer should then decide whether it can wait until after H-1B activation. If the start date must be immediate, the employer needs another lawful work basis, such as OPT, STEM OPT, TN, E-3, O-1, H-1B1, or cap-exempt H-1B. If none exists, the offer may need a delayed start or may not be feasible.

Employers should also budget for the filing. A standard H-1B change of employer filing can include Form I-129 fees, the ACWIA training fee, fraud fee where required, asylum program fee where required, attorney fees, optional premium processing, and any employer-specific fees such as the 9-11 fee for covered employers. Fee responsibility rules matter because certain H-1B costs cannot be passed to the worker if doing so would reduce wages below the required wage. For a deeper hiring-side fee breakdown, see the cost to sponsor H-1B workers.

What are the safest paths if you have a better offer?

The safest path depends on how much risk you and the new employer can accept. These are the most common strategies.

Path 1. Stay through H-1B activation, then transfer

This is usually the cleanest route. You remain with the selected employer until the H-1B change of status takes effect. The new employer prepares the transfer filing in advance and files after you are in H-1B status. If the petition is properly filed and portability applies, you may be able to start with the new employer before approval.

The risk is employment reality. Your first H-1B job should be real. If there was never a genuine job, or you never intended to work for the petitioner, the case can create later USCIS questions. Keep pay records, offer letters, and onboarding records.

Path 2. Start with the new employer on OPT, while the original H-1B continues

This can work only if you have valid OPT or STEM OPT authorization for the new role and the original employer still has a valid job offer and petition. It can become messy because the original H-1B petition is based on future employment with that original employer. If you no longer intend to work there at all, the filing may no longer reflect a real job.

Before choosing this path, get legal advice on whether the original employer can and should keep the petition active. Also confirm that the new OPT role meets F-1 requirements. A high-paying role outside your field of study can create a separate F-1 status problem.

Path 3. Use a cap-exempt employer

If the new employer is cap-exempt, it can file without waiting for the next lottery. This is most useful for candidates moving into universities, affiliated nonprofits, nonprofit research organizations, and government research organizations. It does not preserve the private-sector cap selection, but it may provide an independent H-1B route.

Path 4. Re-enter the lottery next year

If the first petition fails before activation and no other work status is available, the new employer may need to register you in the next H-1B cycle. Under the FY 2027 system announced by DHS on February 27, 2026, selection is weighted rather than purely random. Higher wage and skill factors may affect registration strategy, but the new employer still needs its own registration and selection.

What is the practical takeaway?

You can accept interviews and negotiate offers after H-1B lottery selection, but you usually cannot move the selected H-1B slot to a new employer before October 1. The original employer must file and maintain the cap petition, and portability usually starts only after H-1B status is active or another cap-counted basis clearly exists.

Before resigning, get the receipt or approval notice, confirm whether the case is change of status or consular notification, ask whether the original employer will withdraw, and have the new employer’s immigration counsel write a filing plan. If the plan depends on a “transfer” before October 1, ask counsel to identify the exact legal basis. A selected registration alone is not enough.

Use Avisa to focus your search on employers that understand these timing rules. A strong offer is only useful if the immigration path can support your actual start date.
