Yes, but the answer depends on exactly where your employment-based case stands. A pending PERM labor-certification application belongs to the sponsoring employer and describes that employer’s specific job. It generally cannot be carried to a different company. A new employer normally must begin its own labor-certification and immigrant-petition process.
The major portability rule is different after an employment-based Form I-485 adjustment application has been pending for at least 180 days. Under the American Competitiveness in the Twenty-First Century Act (AC21), some applicants with an approved employment-based immigrant petition may change employers or jobs when the new position is in the same or a similar occupational classification. That rule does not automatically give permission to work for the new company; separate immigration-status and work-authorization rules still apply.
This is general United States immigration information, not a determination of your status or eligibility. The result in an individual case depends on the petition, adjustment filing, job duties, category, priority date, and current work authorization.
What changes are possible at each stage?
The practical consequence of changing employers turns on whether the case is still at the Department of Labor (DOL), has reached USCIS, or has an adjustment application that has crossed the 180-day AC21 threshold.

| Case stage | What changing employers usually means | Key limitation |
|---|---|---|
| PERM pending | The new employer generally starts a new PERM case for its own position. | The pending labor certification is tied to the original employer and job. |
| PERM certified, I-140 not filed | The original employer must decide whether to use the certification; a new employer generally cannot simply take it. | DOL says the certification is valid for 180 days for submission with Form I-140. |
| I-140 pending or approved, but I-485 under 180 days | Do not assume the immigrant petition makes a move portable. A new employer may need a new process. | Approved I-140 alone is not the AC21 portability threshold. |
| I-485 pending 180 days or more | A qualifying applicant may use AC21 portability for a new job in the same or a similar occupational classification. | Category, petition-validity, job-comparison, and work-authorization requirements still apply. |
Can you switch jobs while your PERM is pending?
You can decide to leave an employer, but the pending PERM case does not become a worker-owned application that follows you. PERM is DOL’s process for an employer’s permanent job opportunity. The sponsoring employer obtains the labor certification and later submits it to USCIS with Form I-140.
Because the application describes the original company, position, recruitment, and labor-market test, a move to an unrelated company normally requires the new employer to begin its own PERM case. The new company cannot ordinarily substitute itself into the old employer’s pending application merely because the worker, occupation, or location appears similar.
If the new job is with an affiliated company
Corporate relationships do not automatically make a labor certification portable. Whether a related entity can sponsor you depends on the legal employer, the job opportunity, the filings, and the applicable rules. Treat an affiliate, successor, or reorganization as a document-specific issue rather than assuming the existing PERM can be amended.

A withdrawal or abandonment ends the practical path based on that pending application. It does not transfer the case to your next employer. The new sponsor should evaluate its own recruitment and filing strategy before you rely on the move.
What if PERM is certified but the I-140 has not been filed?
DOL states that a certified labor certification is valid for 180 days for submission to USCIS with Form I-140. That is a deadline for the employer’s use of the certification; it is not a 180-day job-portability period for the worker.

If you leave after certification but before the I-140 filing, the original employer may or may not proceed, depending on its decision and the case facts. A different employer generally cannot simply file the certified PERM as its own. It may need to conduct a new labor-certification process and file a new I-140.
Do not confuse this DOL filing window with AC21’s separate 180-day I-485 rule. They measure different events and create different consequences.
Can you change employers after I-140 approval?
An approved I-140 is important evidence in an employment-based case, but approval alone is not the portability threshold described by USCIS. The AC21 rule centers on a qualifying employment-based I-485 that has been pending for at least 180 days.
If no qualifying I-485 has reached 180 days, you should not assume that the approved petition authorizes an immediate move to another sponsoring employer. The new employer may need to file its own PERM and I-140. Whether an earlier priority date can be retained is a separate question, and the ability to start work for the new company depends on your current immigration status and work authorization.
Individual I-140 withdrawal, revocation, and validity consequences are fact-dependent. An older USCIS interim memorandum contains historical guidance, but USCIS identifies its current Policy Manual as the controlling explanation. Have the actual petition history reviewed before relying on a withdrawal or revocation theory.

How long after filing I-485 can you change jobs?
For AC21 portability, the relevant period is generally 180 days or more with the employment-based I-485 pending. USCIS describes the rule for certain adjustment applicants in employment-based first, second, and third preference categories who have an approved employment-based immigrant petition.
Recommended Free Tools
The 180-day period is tied to the adjustment application, not to the PERM filing date, I-140 filing date, or I-140 approval date. Keep the I-485 receipt and any transfer or procedural notices so the start date can be established from the record.
What if the adjustment case is transferred to a different basis?
USCIS distinguishes portability on the existing basis from a transfer of the adjustment application to another employment-based category using a new I-140. If USCIS approves such a transfer, the 180-day portability period for the new basis starts with the transfer request, according to the Policy Manual. Do not automatically count the original filing period toward the new basis.
Who qualifies for AC21 portability?
The core rule, in USCIS’s wording, allows “certain adjustment applicants with approved employment-based immigrant visa petitions in the 1st, 2nd, and 3rd preference categories to change jobs and employers if the adjustment application has been pending for 180 days or more,” provided the new job is in the same or similar occupational classification as the job for which the original petition was filed.
That description contains several requirements:
- An employment-based I-485 must have been pending for at least 180 days.
- The applicant must have an approved employment-based immigrant petition meeting the applicable category rules.
- The proposed position must be in the same or a similar occupational classification as the original job.
- The case must fall within a category to which the portability provision applies.
- The applicant must separately have authority to work for the new employer.
Categories and exclusions
USCIS identifies exclusions from this particular AC21 portability provision. Approved petitions based on extraordinary ability and national-interest waivers are not eligible under this employer-sponsored portability rule. National-interest-waiver physicians have separate rules, so the ordinary PERM pathway should not be generalized to them.
“Employment-based” is therefore not enough by itself. Confirm the preference category and the basis of the approved petition before treating a job change as portable.

What does “same or similar job” mean?
The comparison is about occupational classification and the actual job offer, not merely whether two titles look alike. A title such as “senior analyst” can cover materially different work, while different titles can describe substantially related occupations.
Evidence to compare
Build a side-by-side record of the original and proposed positions, including the occupational classification used in the filings, core duties, required skills, work location, department, and level of responsibility. Include the written job offers and a clear explanation of how the duties relate. USCIS applies the test to the facts; there is no safe rule that a particular percentage of salary, title, or seniority automatically decides the issue.
Compensation, career progression, and changes in seniority may be relevant facts, but they should not be treated as a complete checklist or guaranteed safe harbor. A substantially different occupation presents more risk than an ordinary progression within the same professional field.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Examples of weak assumptions
- “Both jobs are in technology” is too broad to establish similar occupational classification.
- Keeping the same title does not solve a major change in duties or occupational code.
- A higher salary does not by itself prove that the new role is similar.
- A lower title does not automatically disqualify a move if the duties remain within the same or similar classification.
Does changing employers change your priority date?
Priority-date retention is different from transferring the original PERM or I-140. USCIS says priority dates generally are not transferable between petitions, while regulations permit retention of an earlier date in certain employment-based first, second, and third preference cases.
Whether you can keep an earlier date depends on the petition and regulatory conditions. A new employer may need a new PERM and I-140 even when an earlier priority date is potentially retainable. Conversely, retaining a date does not make the old labor certification portable and does not itself authorize employment.

Can you start working for the new employer?
Green-card portability and permission to work are separate questions. AC21 may support the adjustment case when its requirements are met, but it does not, by itself, answer whether you may begin employment with the new company.
Your ability to work depends on your current nonimmigrant status, an employment authorization document, or another applicable authorization. The answer can change if status has expired, employment has ended, an authorization document is restricted, or the new position does not fit the conditions of the authorization. Do not treat an I-485 receipt, an approved I-140, or an AC21 filing as a universal work permit.
A practical decision process before you resign
- Identify the exact stage. Confirm whether PERM is pending, certified, or expired; whether an I-140 was filed and approved; and the date USCIS received the I-485.
- Collect the controlling documents. Gather the PERM filing information, I-140 approval notice, I-485 receipt, adjustment notices, job descriptions, and current work-authorization documents.
- Check the preference category. Determine whether the approved petition is in an eligible employment-based first, second, or third preference category and whether an exclusion applies.
- Measure the 180-day period. Use the I-485 pending date, not the PERM or I-140 date. If the adjustment basis was transferred, determine which 180-day period applies.
- Compare the jobs. Document the occupational classification and actual duties of both positions. Do not rely on titles alone.
- Evaluate the priority date separately. Ask whether the new petition can retain an earlier date under the applicable rules; do not describe this as transferring the PERM.
- Confirm work authorization. Establish, before starting, which document or status permits employment with the new company and whether its conditions fit the proposed job.
- Coordinate the filings. If AC21 portability is available, follow the USCIS procedure for notifying the agency of the qualifying new offer. If it is not, the new employer should plan its own sponsorship process.
Common mistakes and how to avoid them
- Counting from the wrong filing: The DOL 180-day PERM validity window is not the AC21 180-day I-485 period.
- Assuming I-140 approval is enough: Approval without a qualifying I-485 period does not create the stated portability right.
- Using job titles as proof: USCIS evaluates occupational classification and the real job offer.
- Ignoring category exclusions: Extraordinary-ability and national-interest-waiver cases do not use this employer-sponsored AC21 provision.
- Starting work first: Adjustment portability does not replace separate work authorization.
- Assuming priority-date retention transfers the case: Keeping a date, when allowed, is not moving the old PERM or I-140 to a new employer.
- Relying on outdated summaries: USCIS’s current Policy Manual should be checked against the actual record, particularly for petition withdrawal or revocation issues.
When individualized legal review is warranted
Get an employment-based immigration lawyer to review the file before changing jobs when the I-485 date is close to 180 days, the new role changes occupation or seniority substantially, the petition has been withdrawn or questioned, the adjustment basis has been transferred, the employer is restructuring, or work authorization is uncertain.
A useful consultation should address the exact I-485 pending calculation, approved-petition validity, AC21 category eligibility, same-or-similar evidence, priority-date rules, and the separate authorization to work. Those are distinct decisions; solving one does not automatically solve the others.
