Whether You Can Switch Jobs Depends on One Approval, Not the Other
PERM approval alone gives you almost no flexibility to change employers — an approved Form I-140 gives you real options.
The rules that protect a sponsored employee’s ability to change jobs turn entirely on which document is approved, and how long an adjustment application has been pending. Here is where the line actually falls.
Updated September 18, 2026 · GWP Law · Las Vegas, NVTHE CONTEXT
Can I Change Employers After My PERM or Form I-140 Is Approved?
Rarely after PERM alone; usually yes after I-140 is approved and Form I-485 has been pending 180+ days, in a same-or-similar job.
These two approvals protect the worker in very different ways, and confusing them is the most common mistake sponsored employees make when a new job offer arrives.
After PERM Approval, Before I-140: Almost No Flexibility
A certified labor certification is tied to the sponsoring employer and the exact job described in it, under 20 CFR Part 656.
If the worker changes employers during this window, the certification does not transfer — the new employer must start an entirely new PERM case from scratch.
The one narrow exception: if the original employer files Form I-140 and USCIS approves it before the certification’s validity period runs out, the priority date is preserved even though the worker later moves on.
After I-140 Approval: AC21 Portability Opens the Door
Once Form I-140 is approved, the American Competitiveness in the 21st Century Act (AC21) allows job changes without losing the case, under three conditions.
First, the I-140 must be approved, or approvable when filed. Second, Form I-485 must have been pending 180 days or more. Third, the new job must be in the same or a similar occupational classification as the original one.
USCIS does not rely on a simple job-title or SOC-code match to decide “same or similar” — it weighs the actual duties, required skills, education, experience, and wage of both positions together.
To use this option, the worker and new employer must sign and file Form I-485 Supplement J, notifying USCIS that the new offer is genuine and meets the same-or-similar standard.
What Happens If the Original Employer Withdraws the I-140
Under 8 CFR 205.1, an I-140 withdrawn 180 days or more after its approval, or 180 days or more after the I-485 was filed — whichever comes first — remains valid for portability purposes.
Withdrawn earlier than either of those thresholds, the petition is automatically revoked and can no longer support a portability move under AC21, though the priority date itself is often still available for a future petition.
One outcome overrides all of this: if USCIS revokes the I-140 for fraud, material misrepresentation, or a material error at any point, the revocation applies retroactively and the priority date is lost entirely.

A REAL CASE
An Offer That Almost Fell Outside “Same or Similar”
A software engineer came to me with a competing job offer after his I-485 had been pending for just over a year.
The new title looked different on paper, so I compared the actual duties, required skills, and salary against his original PERM job description.
The core responsibilities matched closely enough to qualify as “same or similar,” and we filed Form I-485 Supplement J with the new employer’s signature.
He started the new job without restarting his green card process, because the underlying occupation — not the title — was what mattered.
What to Do Now
THE PATH FORWARD
Timing Decides More Than the Job Title Does
The difference between losing years of progress and moving freely comes down to two dates: whether I-140 is approved, and how long I-485 has been pending.
For employees still weighing that first decision — adjustment of status versus consular processing — portability under AC21 applies only to the adjustment of status path, which is one more reason to plan that choice early, and to revisit our guide on what comes before I-140 in the first place.
