Portability
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 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 their behalf. The most common scenario is an H-1B worker transferring from Employer A to Employer B. However, portability also applies where the foreign national's current employer requests new employment or a change or amendment of employment terms with the same employer.
Why This Matters
Without portability, H-1B workers would have to wait months for a new petition to be approved before starting work with a new employer — severely limiting job mobility and creating hardship for both workers and employers.
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?
Eligibility Requirements
- 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 — meaning it is filed while you are still in valid H-1B status or in a period of authorized stay.
- You must meet all specialty occupation and qualification requirements for the new H-1B position.
- Your new employer must be a U.S. entity with a valid EIN, must meet all wage and working condition obligations, and there must be a bona fide employer-employee relationship.
- Your new employer must file 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 include: (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.
Timing: Filing vs. Receipt
The timing of when you can begin working for a new employer under portability is a critical detail that is often misunderstood. Getting this wrong can jeopardize your immigration status.
When Can You Start Working?
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. Instead, wait for the official receipt notice from USCIS before starting to work for your new employer.
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.
Best Practices
- Wait for the official USCIS receipt notice (I-797C) before starting work with the new employer.
- File the new petition while you are still employed by your current H-1B employer, before giving notice.
- Do not rely solely on mail or courier delivery confirmations as proof of filing.
The $100,000 H-1B Fee
Recent USCIS guidance has clarified when the new $100,000 H-1B fee applies — and does not apply — to portability petitions. Understanding these rules can save your employer a significant cost.
Portability and the $100,000 H-1B Fee
Based on recent 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.
When the Fee Does Apply
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.
- You are not eligible for the requested extension of status, change of employer, or change of employment terms.
International Travel During Portability
Traveling abroad while your portability petition is pending requires careful planning. The rules vary significantly depending on the status of your original and new H-1B petitions.
Travel Scenarios and Requirements
Scenario 1: Original H-1B and Visa Still Valid, New Petition Pending
If 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, 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: Original H-1B and Visa No Longer Valid, New Petition Pending
If 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 approval, you cannot return to the U.S. until the petition is approved and you obtain a new visa. Your portability petition will also become subject to the $100,000 fee.
Warning
Traveling abroad in this scenario before your new petition is approved can leave you stranded outside the U.S. and trigger the $100,000 fee. Wait for approval before making any travel plans.
Scenario 3: Original Visa Still Valid, New Petition Approved
If 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.
Travel Scenarios at a Glance
| Scenario | Original Visa Valid? | New Petition Status | Can You Travel? | $100K Fee? |
|---|---|---|---|---|
| 1 | Yes | Pending | Yes | No |
| 2 | No | Pending | Not recommended | Yes, if you travel |
| 3 | Yes | Approved | Yes | No (if filed as amendment/extension and approved before departure) |
What Happens If the New Petition Is Denied?
A denial of your new H-1B petition has immediate consequences for your employment authorization and immigration status.
Consequences of a Petition Denial
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.
Key Points
- You must stop working for the new employer immediately upon denial.
- You may be able to return to your original employer if that H-1B petition is still valid and the employer agrees.
- If you have no valid underlying H-1B petition to fall back on, you may be out of status.
H-4 Dependents, Cap Issues & Bridging Petitions
Portability has important implications for your dependents, and the rules differ depending on whether your current and new employers are cap-subject or cap-exempt. Additionally, the concept of bridging petitions introduces both flexibility and risk.
H-4 Dependents and Portability
The H-1B portability provision also covers your dependents, who will maintain H-4 status as long as you are lawfully working under the portability provision.
Cap-Subject vs. Cap-Exempt H-1Bs
H-1B portability works best when moving 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 — including electronic registration, lottery selection, a start date no earlier than October 1 of the applicable fiscal year, and no filing more than six months before the requested start date.
Potential Workaround
If you are moving from cap-exempt to cap-subject employment, one potential workaround 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.
Cap Implications for Portability
| Transfer Direction | Subject to Cap? | Filing Flexibility |
|---|---|---|
| Cap-subject → Cap-subject | No (already counted) | File any time of year |
| Cap-subject → Cap-exempt | No | File any time of year |
| Cap-exempt → Cap-subject | Yes | Must go through registration, lottery, and timing requirements |
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.
Bridging Petition Example
Step 1: Working for Employer A
You are working in H-1B status for Employer A and accept a job offer from Employer B.
Step 2: Employer B Files Portability Petition
Employer B files a portability petition (A→B) on your behalf. Upon receipt, you start working for Employer B.
Step 3: Original I-94 Expires
While the A→B petition is pending, your initial H-1B I-94 with Employer A expires.
Step 4: Employer C Files Another Portability Petition
While working for Employer B, you accept a job offer from Employer C. Employer C files a portability petition (B→C), and you start working for C upon receipt.
Step 5: Risk: Denial of A→B Petition
Since the original I-94 has 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.
Best Practices for Bridging Petitions
- File portability petitions when you still have sufficient time left on your previously approved H-1B petition.
- Use premium processing to get faster decisions and reduce the risk of a bridge collapse.
