Understanding Your Right to Transfer H-1B Employment Under AC21

H-1B portability gives foreign nationals and their U.S. employers greater mobility and flexibility when changing jobs. Established by the American Competitiveness in the Twenty-First Century Act of 2000 (AC21), this provision allows certain H-1B workers inside the U.S. to begin new employment as soon as USCIS receives a qualifying petition. This guide covers eligibility, timing, travel considerations, the $100,000 fee, cap implications, and bridging petitions.

What Is H-1B Portability?

H-1B portability is a powerful provision that allows qualifying H-1B workers to change employers without waiting for a new petition to be fully approved. Understanding how it works is the first step toward a smooth transition.

Overview of H-1B Portability

Portability is a provision under the H-1B nonimmigrant visa category that offers both H-1B workers and their U.S. employers greater mobility and flexibility. It was established by the American Competitiveness in the Twenty-First Century Act of 2000 (AC21).

H-1B portability allows certain H-1B foreign nationals (FNs) who are inside the U.S. to transfer (“port”) to new employment as soon as USCIS receives a new non-frivolous H-1B petition on the FN’s behalf. The most common scenario for this is an H-1B worker transferring from Employer A to Employer B. However, portability also applies where the FN’s current employer requests new employment or a change/amendment of employment terms for the FN with the same employer.

02

Eligibility Requirements

Not every H-1B worker automatically qualifies for portability. You must meet several specific requirements before you can begin working for a new employer under this provision.

Who Qualifies for H-1B Portability?

To qualify for H-1B portability:

  • You must be physically present in the U.S., have been lawfully admitted, and not have engaged in unauthorized employment or otherwise violated your status.
  • The new H-1B petition must be non-frivolous and timely filed, i.e., while you are still in valid H-1B status or in a period of authorized stay.
  • You meet all specialty occupation and qualification requirements for the new H-1B position.
  • Your new employer is a U.S. entity with a valid EIN, meets all wage and working condition obligations, and there will be a bona fide employer-employee relationship.
  • Your new employer files the H-1B petition with a valid certified Labor Condition application (LCA) that covers the position and work location(s).

What Counts as a "Period of Authorized Stay"?

Examples for periods of authorized stay: (1) Your I-94 has expired, but your original H-1B employer filed a timely request for extension of status on your behalf, which is currently pending. (2) You are currently in the discretionary 60-day grace period following the termination of your original H-1B employment.

03

Timing: Filing vs. Receipt

Even though the portability regulations allow you to start new H-1B employment “upon the filing” of a new H-1B petition, you should not rely on a mail or courier service’s delivery confirmation and instead wait for the official receipt notice from USCIS before starting to work for your new employer.

Also, ideally, the new petition should be filed before you leave your current employer, so that you do not have to rely on the discretionary 60-day grace period.

04

Portability and the $100,000 H-1B Fee

Please note

On June 8, 2026, a district court vacated the $100,000 fee, and on July 24, 2026, the First Circuit declined to stay that decision while the government’s appeal is pending. USCIS is currently complying with the court’s order and has paused collection of the fee. However, the situation remains fluid: litigation is ongoing, and on September 18, 2026, President Trump extended the $100,000 fee for another year, until September 21, 2027.

Based on previous guidance from USCIS, an H-1B portability petition on your behalf that requests an extension, a change of employer, or a change in employment terms should not be subject to the $100,000 H-1B fee if:

  • You are inside the U.S. and are eligible for the requested extension or change.

However, your petition will be subject to the $100,000 H-1B fee if:

  • It requests consular notification, port of entry notification, or pre-flight inspection for you, or if
  • You are not eligible for the requested extension of status, change of employer, or change of employment terms.

H-1B Portability and International Travel

What happens if you want to travel abroad after porting to a new H-1B employer? This will depend on several factors:

Scenario 1: Your original, previously approved H-1B petition and visa are still valid, the new H-1B petition is still pending, and you are already working for the new employer.

You may travel in this scenario, as long as the new petition requests an approvable change of employer with an amendment or extension of stay. Your petition will not be subject to the $100,000 fee.

For readmission into the U.S., you should present the following documents:

  • Valid, unexpired passport.
  • Valid, unexpired H-1B visa (unless you are visa-exempt). This can be a previously issued visa endorsed with the name of your original H-1B employer; it will stay valid up to its expiration date.
  • Previous I-797 Approval Notice with the original H-1B petition’s validity dates and your most recent I-94.
  • I-797 Receipt Notice showing that your new H-1B employer’s petition was timely filed.
  • Recent pay stubs from your new employer.

Scenario 2: Your original, previously approved H-1B petition and visa are no longer valid, the new H-1B portability petition is still pending, and you are already working for the new employer.

You should not travel abroad until the new H-1B petition is approved. If you do travel before that, you cannot return to the U.S. until the petition is approved and you obtain a new visa. Your portability petition will become subject to the $100,000 fee. 

Scenario 3: Your original H-1B visa is still valid, and the new H-1B petition has been approved.

You are free to travel and won’t trigger the $100,000 fee, but only if the portability petition was (1) filed as an amendment or an extension of stay, and (2) approved before you leave the U.S. for travel. Otherwise, the $100,000 fee will apply.

For readmission into the U.S., you will need:

  • Valid, unexpired passport.
  • Valid, unexpired visa (unless visa-exempt), which can be the previously issued visa endorsed with the name of your original H-1B employer. There is no need to apply for a new H-1B visa if your previously issued visa is still valid.
  • New I-797 Approval Notice with the new H-1B petition validity dates.
  • Two recent pay stubs from your new employer.

What Happens if the New H-1B Petition Is Denied?

If the new H-1B petition is denied, you are no longer covered by the portability provision and must immediately stop working for the new employer. If the original H-1B petition is still valid and the original employer has no objections, you may return to your original H-1B employment.

07

H-4 Dependents and Portability

The H-1B portability provision also covers your dependents, who will maintain H-4 status if you are lawfully working under the portability provision.

08

Cap-Subject vs Cap-Exempt H-1Bs

H-1B portability works best from one cap-subject employer to another, or from a cap-subject employer to one that is cap-exempt. Since you will have already been counted towards the cap, the new H-1B petition can be filed at any time of the year.

It gets more complicated when you move from cap-exempt to cap-subject employment, since that new petition will now be subject to the cap and to all related process and timing requirements (i.e., electronic registration, lottery selection, start date no earlier than October 1 of the applicable fiscal year, no filing more than six months before the requested start date). One potential workaround for this is to request approval for concurrent employment in a cap-subject position with Employer B while maintaining employment in the cap-exempt position with Employer A.

09

Bridging Petitions

You can have one or more portability petitions filed on your behalf, either simultaneously or successively, as long as each petition separately meets all the requirements for approval. This may be useful if you are weighing multiple H-1B job offers or want to have one or more fallback options.

However, once your initial H-1B I-94 expires while the portability petition(s) are pending, the denial of any filing in the string of portability petitions will make the “bridge” collapse, and you will no longer be in a period of authorized stay.

Example: 

  • You are working in H-1B status for Employer A, and accept a job offer from Employer B. 
  • Employer B files a portability petition on your behalf, and upon receipt, you start working for B. 
  • While the A→B petition is pending, your initial H-1B I-94 with Employer A expires. 
  • While working for Employer B, you accept a job offer from Employer C; C files a portability petition for you (B→C), and you start working for C upon receipt.  
  • Since the original I-94 has since expired, a denial of the A→B petition would cut off the bridge that “held” the subsequent B→C petition, the B→C transfer would be denied as well, and you would no longer be in a period of authorized stay. 

For this reason, it is best to file portability petitions when you still have sufficient time left on your previously approved H-1B petition and to file via government premium processing.
