H-1B During PERM Labor Certification Processing (2026)
The PERM process takes 12-24+ months. Understanding how to extend H-1B status during PERM processing is critical to maintaining work authorization on the path to a green card.
The 6-Year H-1B Cap and PERM Timing
H-1B status has a standard maximum of 6 years (two 3-year periods). After 6 years, you must leave the US for at least one year before obtaining new H-1B status — unless you qualify for extensions beyond 6 years. The key extension mechanisms depend on progress in the green card process: specifically, PERM approval and I-140 approval.
1-Year H-1B Extensions: The 365-Day Rule
Under AC21 Section 106(a), if your PERM labor certification has been pending for 365 days or more, you can obtain H-1B extensions in 1-year increments beyond the 6-year cap. You do NOT need an approved I-140 — only a pending PERM that is at least 365 days old. File the H-1B extension (I-129) with evidence of the pending PERM (ETA Form 9089 receipt).
3-Year H-1B Extensions: Approved I-140 + Backlog
Under AC21 Section 104(c), once your I-140 is approved AND your priority date is not current (backlogged), you can obtain H-1B extensions in 3-year increments beyond the 6-year cap indefinitely. This is the standard mechanism for India and China nationals. You must have an approved I-140 — a pending I-140 alone does not qualify for the 3-year extension.
Strategic PERM Filing Timing
File PERM as early as possible — ideally in year 3 or 4 of your H-1B. DOL PERM processing has historically been 12-18 months (currently longer due to audit volumes). To use the 365-day rule before your H-1B expires, your PERM must have been pending for 365+ days while you still have H-1B validity. Filing PERM in year 5 may not leave enough runway.
Frequently Asked Questions
Can I change employers while PERM is pending?
Yes, under AC21 Section 106(c) — if your I-140 has been approved for 180+ days, you can change to a same or similar occupational classification without abandoning your priority date. Changing employers before I-140 approval means restarting PERM with the new employer.
Does a PERM denial affect my H-1B?
A PERM denial does not directly affect your H-1B status. H-1B is a separate nonimmigrant status maintained independently. However, if PERM is denied, you lose the pending PERM that enabled 1-year H-1B extensions. You can refile PERM with corrections while maintaining H-1B status.
Can I get a 3-year H-1B extension with only an approved I-140 but no backlog?
No. The 3-year extension requires both an approved I-140 AND an unavailable priority date. If your priority date is current, you must either file I-485 or proceed to consular processing — you cannot claim the 3-year extension if a visa number is immediately available.
What is the difference between the 365-day rule and the I-140 approval rule?
The 365-day rule (PERM pending 365+ days) enables 1-year H-1B extensions — useful when PERM is still pending. The I-140 approval rule (approved I-140 + backlogged priority date) enables 3-year H-1B extensions — standard for India/China nationals in the EB backlog.
