Usually, no—not under AC21 portability. A pending PERM belongs to the sponsoring employer, and a pending I-140 does not by itself let you move the green-card case to a new employer. The portability rule generally becomes available only after USCIS has approved the I-140 and the employment-based Form I-485 has been pending for at least 180 days. The replacement job must also be in the same or a similar occupational classification.
Your ability to change jobs safely depends on the exact stage of the case, the employment-based category, whether the original employer withdraws or supports the petition, visa availability, and your underlying nonimmigrant status. The following framework explains what each stage normally means and what evidence to preserve.

At-a-glance answer by case stage
| Case stage | Can you change employers without relying on AC21 portability? | Typical immigration consequence |
|---|---|---|
| PERM pending, no I-140 | You may leave the job as an employment decision, but the pending PERM remains tied to the original employer and job opportunity. | The new employer generally starts a new PERM process and then files its own I-140. |
| I-140 pending, no qualifying I-485 portability | A move does not turn the pending petition into a portable case. | The new employer normally needs its own PERM/I-140 strategy; the original petition must still be adjudicated before USCIS can favorably decide an INA 204(j) portability request. |
| Approved I-140 and I-485 pending fewer than 180 days | The AC21 180-day protection is not yet available. | Changing jobs can put the original adjustment basis at risk. Withdrawal, revocation, and timing facts require individualized analysis. |
| Approved I-140 and I-485 pending 180 days or more | Potentially yes, if the new permanent offer is in the same or a similar occupational classification and all other requirements are met. | The worker and prospective employer generally submit Form I-485 Supplement J and retain evidence supporting the job comparison and bona fide offer. |
The 180-day period is measured from the employment-based I-485 filing, not from the I-140 filing date. A person who has waited 180 days after submitting an I-140 but has not filed an eligible I-485 has not reached the AC21 portability milestone.
If your PERM application is still pending
The certification belongs to one employer and one job
PERM is the U.S. Department of Labor’s labor-certification process for a specific sponsoring employer, position, work location and set of requirements. It is not a worker-owned credential that can be assigned to another company. If you resign or accept a job with a different employer, the pending application ordinarily stays with the original sponsor and cannot be transferred to the new company.
#1 Best Overall
The Department of Labor explains the sequence this way: “After the labor certification application is certified by DOL, it should be submitted to the appropriate USCIS Service Center with a Form I-140.” Certification therefore supports the sponsoring employer’s later I-140; it does not create an open labor certification that any employer can use.
What the new employer normally must do
A new company generally needs to begin its own PERM case. That means confirming the offered position and minimum requirements, completing the required recruitment and notice steps, filing a new application with the Department of Labor, and—if certified—filing a new I-140. Processing times and recruitment obligations can make this a substantial restart rather than a simple employer substitution.
Leaving while PERM is pending also creates a practical question: whether the original employer will continue the case. If it stops, the application may no longer lead to an immigrant petition. If it continues and later files an I-140, that petition still reflects the original employer’s job; it does not automatically cover employment at the new company.

Employment choice versus immigration portability
You can make an employment decision before PERM approval, but the ability to work for the new employer must come from a separate lawful basis, such as an independently available nonimmigrant status or an employment authorization document. The pending PERM itself does not authorize employment and does not protect a job change.
If your I-140 is pending
A filing receipt is not AC21 portability
Filing an I-140, or waiting for USCIS to decide it, does not by itself permit you to port the green-card case to another employer. USCIS states: “If you request to change jobs or employers under INA 204(j) while your Form I-140 is pending, we must approve your Form I-140 before we may approve your portability request.” In practical terms, a pending petition cannot be treated as an approved, portable foundation.
Rank #2
What happens if you move before approval
If you change companies while the first I-140 is pending, the original employer’s petition remains associated with that employer and its offered position. The new employer generally needs a separate PERM and I-140 unless a category-specific rule provides another route. An employment change can also affect whether the original sponsor continues, withdraws, or responds to a request for evidence.
Do not assume that an I-140 approval will retroactively validate a job change made earlier. Portability still requires an eligible adjustment application and satisfaction of the statutory timing and job-similarity requirements. Your nonimmigrant status, work authorization, and the availability of an immigrant visa are separate issues that must remain valid while the case is pending.

The clock people commonly miscalculate
The relevant clock is generally the period that the employment-based I-485 has remained pending. It does not begin when the I-140 is filed, when PERM is filed, or when PERM is certified. For example, filing an I-140 in January and an I-485 in September means the 180-day measurement ordinarily starts with the I-485 filing in September, subject to the rules governing that particular case.
After I-140 approval: before and after 180 days of I-485 pending
Approved I-140, I-485 pending fewer than 180 days
Before the 180-day point, AC21 portability protection is not yet available. A move can jeopardize the employment basis of the adjustment application, especially if the original employer withdraws the offer or the petition is revoked. The consequences depend on whether the employer has withdrawn, whether USCIS has acted on the petition, visa availability, and the facts of the proposed position.
There is no universal safe number of days short of 180. A worker considering a move during this period should obtain case-specific advice before resigning, accepting the new offer, or asking the original employer to withdraw anything.
Approved I-140, I-485 pending at least 180 days
Once the approved I-140 and qualifying adjustment application have reached the required stage, INA 204(j) can allow a move to a new permanent job in the same or a similar occupational classification. This is a potential protection, not an automatic approval. USCIS still examines the category, the validity of the petition, the new offer, job similarity, visa eligibility and the evidence submitted.

How to request portability with Supplement J
Form I-485 Supplement J is the standard document used to confirm a qualifying job offer and request portability under INA 204(j). The worker and prospective employer provide information about the new permanent position and attest to the offer. USCIS may request additional evidence, so submit a comparison that can be understood without relying on assumptions.
- Confirm the timing. Identify the I-485 receipt date and calculate when 180 days of pending time will be reached. Check for any event that could affect whether the application remains pending.
- Confirm the petition. Keep the I-140 approval notice and verify that the approved petition has not been substantively revoked.
- Document the new offer. Obtain a signed, detailed offer describing the title, duties, location, permanent or indefinite nature of the position, full-time expectations and compensation.
- Compare the occupations. Assemble the original and new job descriptions, occupational classification or SOC information where applicable, required education, skills, licenses, duties, wage data and work context.
- Complete Supplement J accurately. The worker and prospective employer should ensure that the form’s descriptions match the supporting documents and the actual position.
- File and retain proof. Keep the submitted form, delivery confirmation, USCIS receipt, correspondence and every document used to establish similarity and the continuing offer.
Supplement J does not replace the requirement that the new position be genuinely available and in the same or a similar occupational classification. It is evidence of eligibility, not a blank authorization to accept any job.
What “same or similar occupational classification” means
USCIS evaluates the totality of the jobs rather than relying only on identical titles. The comparison should address:
- Primary duties and the percentage of time spent on them.
- Occupational classification and SOC information, when applicable.
- Required technical skills, licenses, certifications and tools.
- Education and experience requirements.
- Wage level and compensation, interpreted in the context of the occupation and location.
- Industry, work setting, supervisory responsibility and other relevant context.
A title change does not automatically defeat portability, and an identical title does not guarantee it. A software engineer moving from product development to a role focused almost entirely on unrelated sales duties may face a difficult comparison even if the title remains “engineer.” Conversely, a promotion or move to a different employer with substantially comparable engineering duties may be supportable when the evidence explains the relationship.
The burden is on the applicant to provide evidence. Preserve the PERM-sponsored job description, the I-140 materials, the new employer’s description, organizational information and objective wage or classification records. Explain material differences instead of submitting two titles with no analysis.
Withdrawal, revocation and priority-date protection
An approved employment-based I-140 generally remains valid for priority-date purposes when the employer withdraws it 180 days or more after approval, or when the associated I-485 has been pending for 180 days or more, unless USCIS revokes the approval on substantive grounds. Beneficiaries generally retain the priority date in those circumstances.
This protection preserves the priority date; it does not itself authorize a job change, approve a new position or cure an unapproved I-140. A substantive revocation—such as a finding that the petition was approved in error or involved fraud or willful misrepresentation—can produce a different result. Keep the approval notice and any USCIS correspondence so an attorney can evaluate the exact withdrawal or revocation event.

Employment-based categories
AC21 portability is principally used by qualifying EB-1, EB-2 and EB-3 adjustment applicants. The requirements are not identical across every subcategory. Extraordinary-ability cases and national-interest-waiver cases receive category-specific treatment because the petition may not depend on a conventional employer offer in the same way. Review the USCIS Policy Manual rules for the exact classification rather than assuming that an EB-1, EB-2 or EB-3 label answers every question.
Changing the underlying basis
Moving an I-485 to a different employment-based basis can affect portability and may reset the relevant clock. A transfer is not merely an employer substitution; it can alter the petition, category, priority date and evidence supporting the adjustment application. Obtain advice before requesting a change of basis.
Visa availability and personal status
Portability does not eliminate visa-number limits, admissibility requirements, medical or security checks, or the need to maintain lawful work authorization where required. A job change that is valid under INA 204(j) can still leave a person unable to work lawfully if the separate employment authorization or nonimmigrant-status requirements are not satisfied.
Documents to preserve before changing jobs
- PERM filing, recruitment and certification records, including the sponsored job description.
- I-140 receipt and approval notices, the priority date and the petition category.
- I-485 receipt notice showing the filing date, plus notices for transfers, requests for evidence or interviews.
- Original and proposed job descriptions, organizational charts and duty percentages.
- SOC or other occupational-classification information, required skills, education and licenses.
- Offer letters, wage records and evidence that the new position is permanent or indefinite and bona fide.
- Completed Supplement J, delivery proof and any USCIS response.
- Records of employer withdrawal, termination, merger, acquisition or other event affecting the original petitioner.
Do not discard documents because a case has moved to a later stage. USCIS may need the original PERM and petition evidence to understand why the new position is same or similar.

Practical examples
Example 1: PERM pending, new company offers a better role
The worker may accept the new company’s offer if separately authorized to work, but the first company’s PERM does not follow the worker. The new company should plan for its own PERM and I-140. Continuing to list the old PERM as if it belonged to the worker would misstate the case.
Example 2: I-140 filed, I-485 not yet filed
The worker changes employers two months after the I-140 filing. There is no qualifying I-485 portability period to count. The pending petition remains tied to the original employer, and the new employer normally needs an independent immigration strategy.
Example 3: I-140 approved, I-485 pending 90 days
The worker has an approved petition but has not reached 180 days of I-485 pending time. Filing Supplement J at day 90 does not create the missing eligibility. The worker should analyze withdrawal and status risks before moving.
Example 4: I-140 approved, I-485 pending 210 days
The timing element may be met. The worker and new employer can prepare Supplement J and evidence that the replacement position is same or similar. USCIS can still question the petition’s validity, the job offer, the occupational comparison or another adjustment requirement.
