Can You Change Employers During H-1B Processing?

You can change employers during H1B processing, and you usually do not have to wait for USCIS to approve the transfer before starting the new job. A rule called portability lets you begin work for the new employer the moment a proper petition is filed on your behalf, as long as you meet a short list of conditions. The mechanics matter, though, because a misstep on timing, travel, or unauthorized work can cost you your status.

How H1B Portability Lets You Start Work Right Away

Under 8 U.S.C. 1184(n), you can begin working for a new H1B employer as soon as that employer properly files a nonfrivolous H1B petition for you, or as of the requested start date on the petition, whichever comes later.¹ That work authorization continues for the entire time USCIS has the petition under review.²

Three conditions must be true for portability to apply:

You were lawfully admitted to the United States.
The new employer filed the petition before your current authorized stay expired.
You have not worked without authorization since your last lawful admission.

All three come straight from the statute. Miss any one and portability is off the table. A petition filed a single day after your I-94 expired does not qualify, and any past unauthorized work permanently disqualifies you from using portability at all.¹

What the New Employer Actually Files

Only the employer can file. You cannot submit these forms yourself.

The employer first files a Labor Condition Application with the Department of Labor certifying that the position meets U.S. wage and working condition standards.³ Once the LCA is certified, the employer files Form I-129 with USCIS, along with the job offer details, evidence that the position qualifies as a specialty occupation, and your educational credentials. Foreign degrees may need a credential evaluation showing they are equivalent to a U.S. bachelor’s or higher.

The Form I-797 receipt notice USCIS issues after filing is your proof the transfer is pending. Keep a copy on you, especially before any travel or I-9 conversation with the new employer.

Who Pays the Fees

Federal rules bar the employer from passing most H1B fees on to you. The employer covers the Form I-129 base filing fee plus:⁴

ACWIA fee of $750 for employers with 25 or fewer full-time employees, or $1,500 for larger employers.
Fraud Prevention and Detection fee for initial H1B and change-of-employer petitions.
Asylum Program fee of $600 for employers with more than 25 employees, $300 for smaller employers, and $0 for nonprofits.
An additional $4,000 under Public Law 114-113 for employers with 50 or more U.S. employees where more than half hold H1B or L-1 status.⁵

If your new employer wants a faster decision, it can request premium processing, which guarantees USCIS action within 15 business days. Effective March 1, 2026, the premium processing fee for an H1B I-129 is $2,965.⁶ Fee amounts change, so check the current USCIS Fee Schedule (Form G-1055) before filing.

What Happens if USCIS Denies the Transfer

This is the main risk baked into portability. If USCIS denies the new employer’s petition, your portability-based work authorization ends immediately.¹ You must stop working for the new employer the day the denial comes down.

Where that leaves you depends on what happened with your prior job. If your original employer’s H1B petition is still valid and that employer is willing to take you back, you can resume work under the original petition without any new filing. If you already resigned and the original petition was withdrawn, you are out of status from the day the new employment ended. The 60-day grace period would then apply from that last day, giving you time to line up another petition, change to a different status, or leave the country.⁷

Because of that exposure, many immigration attorneys suggest not resigning your current job until the new petition is at least receipted by USCIS, and some prefer to wait for approval. That is not always practical, but at minimum, hold off on burning bridges with your current employer until you have the I-797 receipt in hand.

Traveling Abroad While the Transfer Is Pending

International travel during a pending change-of-employer petition can undo the transfer. If the petition includes a request for a change of status, leaving the country causes USCIS to treat that request as abandoned. USCIS may still approve the underlying petition, but only as a consular notification, meaning you would need to apply for a new H1B visa stamp abroad and be admitted at a port of entry to regain H1B status.²

Re-entry is possible if you already have a valid, unexpired H1B visa stamp in your passport. Carry your I-797 receipt notice, a letter from the sponsoring employer confirming your position, and your passport. If the stamp has expired, or if the petition requests a change of status rather than a same-visa employer switch, the safer move is to hold off on travel until approval.

If You Were Laid Off Before Finding a New Employer

Termination triggers a grace period of up to 60 consecutive days to find a new sponsoring employer, change to another status, or depart. The clock starts the day employment ends and cannot extend past your I-94 expiration.⁷ If your I-94 expires in 30 days, your grace period is 30 days.

You cannot work during the grace period unless a new employer files a petition and portability kicks in. The regulation permits this grace period only once during each authorized validity period. If you start a portability-based job and that one also ends before your H1B validity expires, there is no second 60-day window.⁸

Losing employer-sponsored health coverage is a practical side effect worth planning around. COBRA continuation is generally available regardless of immigration status and lets you keep the same plan for up to 18 months at your own expense.

Moving From a Cap-Exempt Employer to a Cap-Subject One

If you currently work for a cap-exempt organization such as a university, a nonprofit research institution, or a government research lab, a move to a private company that is subject to the annual cap is not a simple transfer. Your new employer’s petition must go through the annual H1B electronic registration and lottery, which typically opens in March for an October 1 start.⁹

Two exceptions matter. If you were previously counted against the H1B cap at any point, you generally do not have to go through the lottery again. And you can work concurrently for a cap-subject employer while keeping your cap-exempt job: as long as the cap-exempt position continues, you can begin the cap-subject work once that employer properly files its petition.⁹

When You Need an Amendment Instead of a Transfer

Not every change requires a new-employer petition. If your current employer moves your worksite to a different metropolitan area, materially changes your job duties, or alters other significant terms of employment, the employer must file an amended H1B petition rather than a transfer.¹⁰

A transfer always means a new employer and a brand-new I-129 petition, and it triggers portability rights along with a new LCA. An amendment updates the existing petition with the same sponsor. If your employer is simply relocating you across the country, that is an amendment, not a transfer.

What Unauthorized Work or Overstay Can Cost You

Starting work for a new employer without a filed petition, or continuing to work after a denial, is unauthorized employment. It makes you deportable as a nonimmigrant status violator.¹¹ It also disqualifies you from ever using portability again, because one of the three portability requirements is no unauthorized work since your last lawful admission.¹

Overstaying your authorized period triggers unlawful presence bars. More than 180 days but less than one year of unlawful presence results in a three-year bar on re-entry if you leave before removal proceedings begin. One year or more results in a ten-year bar.¹² The bars apply when you leave and try to come back, not while you remain in the country, but they can effectively lock you out for years.
