H-1B Extension of Stay
An H-1B visa is initially valid for 3 years and can be extended once for a total of up to 6 years.
An H-1B visa is initially valid for 3 years and can be extended once for a total of up to 6 years. After the 6-year maximum, the worker generally must leave the U.S. for at least one year before re-applying for H-1B status. However, under the AC21 Act, if the beneficiary has filed a PERM labor certification before the end of the 5th year in H-1B status, or has an approved I-140 immigrant petition, they may extend H-1B status beyond the 6-year cap in increments of 1 year or 3 years. This allows H-1B holders awaiting green card processing to continue working legally in the United States.
Currently in valid H-1B status
The employer is willing to continue sponsorship and file an I-129 extension petition
The position continues to qualify as a "specialty occupation"
Extensions within 6 years: the employer simply files a new I-129
Extensions beyond 6 years (AC21 §106): a PERM application must have been filed at least 365 days before the H-1B 6-year expiration
Extensions beyond 6 years (AC21 §104(c)): an approved I-140 allows 3-year extensions
Determine Extension Eligibility
Confirm current H-1B validity dates and whether the extension is within the 6-year cap or requires AC21 provisions for beyond-6-year extensions.
LCA Update
If the position, work location, or salary has changed, a new LCA must be filed with the DOL. If unchanged, the existing LCA may be used.
File Form I-129
The employer files the I-129 extension petition with supporting documents. For beyond-6-year extensions, include PERM receipt or I-140 approval notice.
Await Adjudication
Regular processing takes 3-6 months. Premium processing (15 business days) is available for expedited results.
Approval and Continuation
Upon approval, a new I-797 approval notice is issued, extending H-1B status to the new validity date.
| Stage | Duration |
|---|---|
| LCA (if update needed) | 7 business days |
| I-129 Preparation | 1-2 weeks |
| Regular Processing | 3-6 months |
| Premium Processing | 15 business days |
Normally 6 years total. However, if a PERM has been filed or an I-140 is approved, AC21 allows indefinite extensions (in 1-year or 3-year increments) until the green card is obtained.
