H-1B Transfer: How to Switch Employers Without Re-Entering the Lottery
By Muntasir Minhaz • Published Aug 19, 2026
H-1B portability lets you start working for a new employer once it files Form I-129 for you and you hold the receipt notice, before USCIS approves the transfer. You skip the lottery, since you already hold cap-counted H-1B status.
📩 New employer files Form I-129, no new registration or lottery
⏱️ Start the new job once you hold the I-797C receipt notice, not the approval
You need unbroken valid H-1B status with no unauthorized work
🛂 If the new petition gets denied, portability-based work authorization ends
Why you skip the lottery
People often call this an "H-1B transfer," though USCIS does not use that term on its forms. A new employer files a fresh H-1B petition for you, using your existing cap eligibility rather than a new lottery entry, since the lottery applies only the first time USCIS counts you against the annual cap.
Your cap number carries with you for the rest of your career, along with the H-1B years you have already used toward your six-year maximum. A new employer's petition does not reset that count.
This holds true whether you change employers directly, or your current employer amends your existing petition to reflect a new role, worksite, or terms.
The portability rule
Section 105 of the American Competitiveness in the Twenty-First Century Act (AC21), codified at INA 214(n), lets you begin working for a new H-1B employer as soon as that employer files a non-frivolous Form I-129 petition on your behalf, without waiting for USCIS approval. Proof of filing sits in your Form I-797C receipt notice, which USCIS typically issues within days of receiving the petition. Most employees and employers wait for the receipt notice before the new job starts, since starting before you prove the petition was filed voids the protection.
Portability eligibility requires lawful admission to the US, valid H-1B status (or another status that permits H-1B portability), and a clean record with no unauthorized work. A break in status, even a brief one, breaks your eligibility to port.
Step by step
| Step | What happens |
|---|---|
| 1 | New employer prepares a Labor Condition Application and gets it certified by the Department of Labor |
| 2 | New employer files Form I-129 with USCIS as a change of employer |
| 3 | USCIS issues Form I-797C receipt notice, usually within days |
| 4 | You start working for the new employer once you hold the receipt notice |
| 5 | USCIS approves or denies the petition, confirming or ending your portability-based work authorization |
What your new employer files
Your new employer files Form I-129 , Petition for a Nonimmigrant Worker, with the H-1B classification supplement, a new Labor Condition Application certified by the Department of Labor for the new position, and supporting evidence of the job and your qualifications. This uses the same core form as an original H-1B petition, filed as a change of employer rather than as new cap-subject employment.
Because a change-of-employer H-1B falls outside new cap-subject employment, it also sits outside the $100,000 payment created by the September 2025 presidential proclamation, which the government's own guidance limits to new H-1B petitions, not transfers, per the USCIS H-1B FAQ . As of August 2026, that fee requirement also sits vacated by a federal court and uncollected while the government's appeal continues, so confirm the current status with your employer's counsel regardless.
Timing risks to manage
Do not resign your current job before your new employer files the petition and you hold the I-797C receipt notice.
Requesting premium processing commits USCIS to a decision within 15 business days, cutting the time you spend on portability-based status before a final approval.
If the new petition gets denied, your authorization to work for the new employer under portability ends immediately. Keep your old job available as a fallback until the new petition gets approved, if that option exists.
If your current H-1B nears its six-year maximum, confirm with your new employer's counsel whether you qualify for an extension beyond six years, since that eligibility does not transfer automatically without matching evidence.
Before you start the new role
Ask your new employer's immigration team for a copy of the I-797C receipt notice before your first day. Keep a copy of your last pay stub and termination date from your old employer, since gaps in authorized work history complicate future filings, including a future green card case. If your circumstances run complex, prior H-1B extensions beyond six years, a pending green card case, or time recently spent outside the US, talk to an immigration attorney before you resign.
H-1B extensions beyond six years
If you already have a pending labor certification or I-140 filed at least 365 days before your sixth year ends, AC21 Section 106(a) lets your new employer request a one-year extension beyond the six-year limit. If your I-140 is already approved but a visa number is not yet available for your priority date, AC21 Section 106(b) allows three-year extensions instead. Your new employer's petition needs evidence of that earlier filing or approval, since this extension eligibility does not move with you automatically, your new employer's attorney has to document it in the new I-129 petition.
What happens to your dependents
H-4 dependents, your spouse and children under 21, need their own Form I-539 application to extend or change status once your new H-1B petition gets approved, filed separately from your I-129. Time this alongside your own filing so your family's status does not lag behind yours, especially if your spouse holds an H-4 EAD tied to your H-1B status.
