Green Card Compliance

I-140 Approved: Changing Employers & Priority Dates

Understand the 180-day rule. Learn how to protect your place in the green card queue and transfer your priority date safely.

What is Priority Date Retention?

In the U.S. employment-based green card process (EB-2 or EB-3 categories), your **Priority Date** is your place in line. It is established on the day your employer files your PERM Labor Certification (or Form I-140 for self-petitioned categories like NIW).

Once your Form I-140 immigrant petition is approved, that priority date is **permanently locked to your profile**. If you decide to change jobs, you do not lose your spot in line. Your new employer will need to file a new PERM and I-140, but they can request to **port (transfer)** your original priority date, letting you bypass the wait lists.

The Critical 180-Day Protection Rule

One of the most important compliance protections under U.S. immigration regulations is the **180-day rule** following Form I-140 approval:

The 180-Day Approval Threshold: Once your Form I-140 has been approved for **at least 180 days**, the petitioner (your employer) cannot revoke or withdraw the petition to cancel your priority date, nor can they block your future H-1B extensions.

Even if the employer withdraws the I-140 or goes out of business after the 180-day mark, the I-140 remains valid for you to:

Retain and port your priority date to any new employer.
Secure infinite **3-year H-1B extensions** past your standard 6-year limit with any new employer.

Priority Date Retention vs. AC21 Job Portability

Expats often confuse these two concepts. They operate under completely different rules depending on where you are in the green card timeline:

Feature	I-140 Approved (I-485 Not Filed)	I-485 Pending for 180+ Days
Process Reset Required?	Yes	No
How it works	New employer must file a new PERM and I-140, then request your original priority date.	You can change jobs in a "same or similar" occupation without restarting. Simply file Supplement J.
H-1B Extension Basis	Approved I-140 enables 3-year extensions with any employer.	Pending I-485 or approved EAD/AP permits you to work without H-1B extensions.

Steps to Safely Switch Employers

Follow this checklist when transitioning to a new employer after I-140 approval:

Wait for the 180-Day Approval Window

Crucial: Do not resign from your current job until your Form I-140 has been approved for at least 180 days to protect your priority date and extension rights.

File H-1B Transfer (Change of Employer)

Your new employer files an H-1B transfer petition. You can start working for the new employer as soon as you receive the USCIS receipt notice, though waiting for approval is safer.

Initiate New PERM & I-140 Porting

The new employer launches your new PERM and I-140. They will attach a copy of your previous approved I-140 approval notice (I-797) to the application package to port your original priority date.
