AC21 Job Portability
AC21 job portability can allow a qualifying employment-based adjustment applicant to change jobs or employers without losing the underlying immigrant petition when Form I-485 has been pending for at least 180 days and the new permanent job is in the same or a similar occupational classification.
What is AC21 job portability?
Current 8 C.F.R. §245.25 also permits a qualifying new offer from the original petitioner, a different U.S. employer, or a qualifying self-employment arrangement.
Basic AC21 portability requirements
Qualifying I-140
The adjustment application must be based on an employment petition eligible for §204(j) portability.
Pending I-485
The qualifying adjustment application must have been pending for at least 180 days.
New Permanent Job
The applicant must have a bona fide new full-time permanent employment offer.
Same or Similar
The new job must be in the same or a similar occupational classification as the qualifying I-140 position.
Supplement J
The applicant generally requests portability by submitting Form I-485 Supplement J.
Valid Petition
The underlying I-140 must satisfy the regulatory validity requirements and cannot be revoked on another substantive ground.
Which categories can use INA §204(j)?
Portability principally applies to qualifying employment petitions in the first three employment-based preference categories when the immigrant classification depends on a specific job offer.
| Classification | §204(j) Portability |
|---|---|
| EB-1A Extraordinary Ability | No. The classification does not require a specific job offer, so ordinary §204(j) portability is unnecessary. |
| EB-1B Outstanding Professor or Researcher | Potentially yes, when all portability requirements are satisfied. |
| EB-1C Multinational Manager or Executive | Potentially yes, subject to the qualifying I-140 and same-or-similar requirements. |
| EB-2 PERM | Yes, when the statutory and regulatory requirements are satisfied. |
| EB-2 NIW | No ordinary §204(j) portability because USCIS has waived the specific job-offer requirement. |
| EB-3 | Yes, for qualifying skilled worker, professional, and other-worker cases. |
| Schedule A | Potentially yes because the underlying I-140 is ordinarily job-offer based. |
| Physician NIW | Not under ordinary AC21 portability. Physician NIWs use their own regulatory rules for changing qualifying employment. |
| EB-5 | No. EB-5 is an investor classification rather than a qualifying I-140 job-offer petition. |
The Form I-485 must be pending for at least 180 days
The portability clock ordinarily begins on the receipt date of the properly filed Form I-485. Section 204(j) becomes relevant only after the application has remained unadjudicated for at least 180 days.
The 180-day portability period is based on the Form I-485 filing and pendency, not the I-140 priority date, I-140 approval date, PERM filing date, or the date the applicant started working for the employer.
An applicant considering an employment change near the 180-day point should verify the USCIS receipt date and actual case posture rather than relying on an approximate calendar calculation.
The underlying I-140 can be approved or still pending
Current regulations allow portability in appropriate cases involving either an already approved I-140 or a qualifying petition that remains pending when the applicant invokes portability after the I-485 has been pending at least 180 days.
If the I-140 remains pending, USCIS must still adjudicate it. The petition must have been eligible for approval under the applicable regulatory standard; portability does not cure a petition that was substantively defective.
The passage of 180 days does not force USCIS to approve an I-140 that lacked eligibility when filed. The petition must satisfy the special portability adjudication rules in 8 C.F.R. §245.25.
Special ability-to-pay rule for a pending I-140
Ordinarily, a job-offer-based petitioner must establish ability to pay the proffered wage beginning at the priority date and continuing until the beneficiary obtains permanent residence.
When a qualifying pending I-140 becomes subject to the regulatory portability provisions, 8 C.F.R. §245.25 limits the original petitioner's continuing ability-to-pay requirement in the manner specified by the regulation. USCIS evaluates whether the petition was eligible for approval through the point at which the associated I-485 had been pending for 180 days.
This special rule is important when the original employer later suffers financial problems or the applicant ports to another employer.
The new job must be full-time and permanent
USCIS Supplement J instructions describe portability as a change to a new full-time permanent job offer that the applicant intends to accept once adjustment is approved.
The new employment does not have to begin with the original employer, and the new employer generally does not need to file another I-140 solely to invoke §204(j).
The applicant and intended employer must demonstrate genuine intent for the applicant to work under the new employment offer within a reasonable period after permanent residence is granted.
For the broader job-offer rule, see Job Offer Requirement at Filing and Approval.
What does “same occupational classification” mean?
Under 8 C.F.R. §245.25, a same occupational classification is an occupation that resembles in every relevant respect the occupation for which the underlying employment petition was approved.
A new position need not necessarily use the identical employer job title. USCIS looks to the occupation itself and the relevant evidence concerning the work.
What does “similar occupational classification” mean?
The regulation defines a similar occupational classification as one that shares essential qualities or has a marked resemblance or likeness with the occupation underlying the qualifying petition.
The analysis is therefore broader than comparing job titles.
| Evidence | Potential Relevance |
|---|---|
| Job Duties | Compares the actual functions performed in the original and new positions. |
| SOC Codes | Can provide useful occupational classification evidence but are not necessarily dispositive by themselves. |
| Skills | Shared technical or professional skill requirements can support similarity. |
| Education | Comparable educational requirements may demonstrate related occupational character. |
| Experience | Similar experience requirements can support a relationship between positions. |
| Wages | May be considered as one factor, but wage differences do not automatically establish that positions are dissimilar. |
| Career Progression | A promotion or advancement can remain within a same or similar occupational path. |
A promotion can qualify for portability
AC21 does not require an employee to remain frozen at the same career level indefinitely. A new job may involve greater responsibility, supervision, management, specialized expertise, or a more senior title while remaining sufficiently related to the original occupation.
For example, progression from a technical professional role into a closely related supervisory or management position may be supportable where the new responsibilities represent normal career advancement and retain the essential occupational relationship.
The portability filing should explain the progression rather than relying exclusively on job titles or occupational codes.
A higher salary does not automatically prevent portability
Compensation can change substantially during a long employment-based green card process because of inflation, geographic differences, promotions, specialized experience, labor-market conditions, or employer compensation structures.
USCIS may consider wage evidence, but a salary difference by itself does not necessarily establish that the jobs are different occupations.
The strongest same-or-similar analysis considers duties, skills, experience, education, occupational classification, career progression, wages, and the overall relationship between the original and new work.
The new employer can be in a different industry
Portability focuses primarily on the applicant's occupational classification rather than whether the two employers sell the same product or operate in the same industry.
A software engineer, accountant, researcher, or other professional may potentially perform sufficiently similar work for employers in very different industries.
Industry differences can still matter when they materially change the applicant's duties, knowledge requirements, or occupational role.
Self-employment can potentially qualify
8 C.F.R. §245.25 expressly recognizes a new employment offer based on self-employment as a possible portability arrangement.
A self-employment case should establish that the proposed work is bona fide, permanent, and in the same or a similar occupational classification as the original petition.
Evidence may include:
- Business formation documents.
- Business licenses.
- Contracts and client arrangements.
- Business plans and operating records.
- Evidence of actual or prospective business activity.
- A detailed description of the applicant's duties.
- Evidence connecting those duties to the original occupation.
Supplement J is the portability request
A qualifying applicant generally invokes portability by submitting Form I-485 Supplement J.
The supplement identifies the new employer, job duties, occupational information, compensation, work location, and other facts USCIS uses to determine whether the new employment satisfies §204(j).
Both the applicant and the employer or authorized employer representative must complete the portions required by the form and provide the necessary certifications and signatures.
Can the applicant change jobs before 180 days?
An applicant may physically leave the original employer before the I-485 has been pending 180 days, but the immigration consequences can be significant.
If the permanent job offer supporting the I-485 disappears before §204(j) becomes available, the pending adjustment application may no longer have a valid employment basis.
Whether the case survives can depend on the timing of the employer's withdrawal, the I-140's status, continued existence of the permanent offer, and whether another immigrant basis is available.
An EAD may permit the applicant to work for another employer before day 180, but work authorization does not itself make that new job a valid §204(j) replacement for the permanent employment underlying the I-485.
Employer withdrawal after 180 days
Current regulations provide significant petition-validity protection once specified 180-day thresholds are satisfied. An approved I-140 is not necessarily automatically revoked merely because the petitioning employer later withdraws it.
However, petition validity and the permanent job offer are distinct concepts. If the original employer no longer offers the job, the applicant generally needs qualifying new employment under §204(j) in order to continue a job-offer-based adjustment case.
A later page in this employment series addresses I-140 withdrawal in greater detail.
Employer termination or business closure
The same general distinction applies when the original employer ceases operations. The business closure may eliminate the original permanent job without necessarily destroying every immigration benefit associated with an otherwise protected approved petition.
If portability is available, the applicant should establish a qualifying new permanent offer promptly and notify USCIS through the proper procedure.
Portability cannot cure fraud or a defective petition
INA §204(j) protects a qualifying immigrant petition; it does not erase a substantive defect in the petition itself.
USCIS may still deny or revoke the petition for independent reasons, including:
- The beneficiary lacked the qualifications required for the original classification.
- The labor certification or underlying employment basis was invalid.
- The petitioner did not satisfy a required eligibility element.
- The petition involved fraud or willful misrepresentation.
- The petition is revoked on another lawful ground.
If the qualifying petition is lawfully revoked on a ground independent of the employment change, the portability request cannot preserve the I-485.
Portability is different from transferring the underlying basis
AC21 portability keeps the qualifying original employment petition connected to the adjustment application while substituting a qualifying new employment offer.
A transfer of underlying basis instead asks USCIS to adjudicate the pending I-485 through a different immigrant petition or category.
See Transfer of Underlying Basis / Interfiling.
USCIS policy provides that an applicant who transfers a pending I-485 to a different employment-based petition generally must wait 180 days after the transfer request before using portability based on the new employment basis.
Visa retrogression does not stop the portability clock
An employment-based Form I-485 may remain pending because the priority date retrogresses. That continued pendency can allow the 180-day portability period to run even though USCIS cannot approve the adjustment until a visa becomes available again.
This is one reason §204(j) is particularly important in long-backlogged categories: applicants may change employers or advance professionally while waiting for final visa availability.
Changing from employee to manager
A move into management can be either a normal progression within the original occupational field or a departure into a materially different occupation.
Useful evidence may include:
- The technical or professional functions that remain part of the new role.
- The applicant's continued use of the same specialized knowledge.
- The relationship between supervised functions and the original occupation.
- The applicant's career trajectory.
- Comparable occupational data.
A detailed factual explanation is usually more persuasive than simply asserting that both jobs belong to the same general industry.
Evidence for an AC21 portability request
- Form I-485 receipt notice showing at least 180 days of pendency.
- Form I-140 receipt or approval notice.
- Properly completed Form I-485 Supplement J.
- Original job description.
- New job description.
- Detailed comparison of duties.
- SOC or O*NET evidence where useful.
- Education, experience, and skill requirements.
- Salary and compensation information.
- Evidence explaining career progression.
- Employer documentation confirming the permanent job.
- Business evidence for a self-employment portability case.
Common AC21 portability problems
Porting Before Day 180
The original job disappears before the applicant reaches the statutory portability threshold.
Unrelated New Occupation
The new work shares too few essential qualities with the occupation underlying the I-140.
Invalid I-140
The underlying petition contains an independent defect that portability cannot cure.
No Permanent Offer
The replacement employment is temporary, speculative, or otherwise not a bona fide permanent position.
Poor Same-or-Similar Evidence
The filing relies only on job titles or SOC codes without explaining the actual duties and occupational relationship.
Transfer Clock Overlooked
The applicant recently transferred the I-485 to another employment petition and assumes the original portability clock still controls.

Frequently asked questions
Can I change employers after my I-485 has been pending 180 days?
Potentially. The new job must satisfy the statutory and regulatory requirements, including the same-or-similar occupational classification standard.
Does my I-140 have to be approved before I port?
Not necessarily. Current regulations permit portability involving certain pending I-140 petitions, but USCIS must still determine that the petition satisfies the required eligibility standard.
Can my salary be higher in the new job?
Yes. A higher salary does not automatically defeat portability. Compensation is only one part of the overall occupational comparison.
Can I port to a promotion?
Yes, if the new position remains in the same or a similar occupational classification. Normal career progression can support a portability finding.
Can I port to self-employment?
Potentially. Current regulations recognize qualifying self-employment, but the applicant must establish a bona fide permanent employment arrangement and same-or-similar occupation.
Do I need a new I-140 when I use AC21 portability?
Ordinarily no. Section 204(j) is designed to preserve the qualifying original petition while allowing a qualifying new permanent job offer.
AC21 portability can preserve years of employment-based immigration processing.
