AC21 Same or Similar Job Portability Under INA 204(j)

Under AC21, the same or similar job portability rule lets you change employers, accept a promotion, or move into self-employment while your employment-based green card application is pending, as long as your Form I-485 has been sitting with USCIS for at least 180 days, you have an approved or approvable Form I-140, and the new position falls within the same or a similar occupational classification as the job described in the original petition. The mechanism for confirming the move is Form I-485 Supplement J, signed by you and your new employer.

Who Can Use AC21 Portability

Portability under INA 204(j) is available to applicants in the EB-1, EB-2, and EB-3 preference categories. EB-4 special immigrants and EB-5 investors cannot use it. Two subgroups follow separate rules: EB-1A extraordinary ability applicants don’t need a job offer in the first place, and EB-2 physicians with a national interest waiver have their own process for changing employers before completing the service commitment.¹

Four conditions have to be satisfied before you can port:

Your Form I-485 must have been properly filed and pending with USCIS for 180 calendar days or more. The clock starts on the receipt date shown on your I-797C and counts every calendar day.
You must be the beneficiary of an approved Form I-140, or of a pending I-140 that is later approved. A petition that was approvable when filed can still support portability even if it hasn’t been adjudicated yet.
The new job must be in the same or a similar occupational classification as the position described in the original I-140 or labor certification.
You must actually request portability, generally by filing Form I-485 Supplement J.¹

The 180-day threshold is rigid. USCIS will reject a Supplement J filed before the I-485 has been pending that long.²

How USCIS Decides Whether Two Jobs Are Same or Similar

This is where most portability cases succeed or fail. USCIS doesn’t demand identical titles or duplicate job descriptions. A “same” occupation matches the original in virtually every respect. A “similar” occupation shares essential qualities or has a marked resemblance to the original, even if the titles differ. Officers weigh the totality of the circumstances and decide by a preponderance of the evidence, not on any single factor.³

SOC Codes

The Department of Labor’s Standard Occupational Classification system is the primary framework. SOC codes have six digits organized in a hierarchy of major groups, minor groups, broad occupations, and detailed occupations. When all six digits match between the old and new positions, officers generally treat that as favorable evidence of the same classification. When the jobs share a broad occupation code but sit in different detailed codes, officers generally treat that as favorable evidence of a similar classification.³ SOC codes are not the only factor, though, and a broad-level match won’t rescue an application if other evidence points the other way.¹

Duties, Skills, Education, and Wages

Officers also compare the specific duties of each position, the skills and experience required, the education or training needed, and any licenses or certifications the work demands.³ Big gaps in required expertise or educational prerequisites can push USCIS toward a finding that the roles aren’t sufficiently related.

Wages matter, but not the way many applicants assume. A salary difference by itself does not disqualify two positions. USCIS recognizes that pay changes with normal raises, geographic cost differences, moves between for-profit and nonprofit employers, or differences in employer size. If there is a substantial pay gap, explain it in detail so the officer can weigh the explanation against the other evidence.¹

Moving Into Management

Promotions from a technical role into a managerial role in the same field are one of the most common porting situations, and USCIS has addressed them directly. The evidence may be treated favorably when the new manager oversees the same functions the applicant previously performed, or manages workers whose jobs fall in the same occupational classification as the applicant’s original position. USCIS’s policy manual uses a Software Developer (SOC 15-1252) moving into a Computer and Information Systems Manager role (SOC 11-3021) as an example that qualifies as similar.¹

Self-Employment

You can port to your own business. USCIS explicitly allows self-employment under INA 204(j), as long as the self-employed position meets the same-or-similar standard and the other eligibility requirements are satisfied. You need enough documentation to show that the business is real and the job offer is legitimate; thin evidence or fraud indicators will draw a Request for Evidence.¹

Scrutiny is often higher here because USCIS also asks whether the original petition represented genuinely intended employment when it was filed. If the timeline suggests the sponsored job was never really meant to happen and was only a stepping stone to self-employment, that can sink the portability claim.

Filing the Portability Request

The document you file is Form I-485 Supplement J, titled “Confirmation of Valid Job Offer or Request for Job Portability Under INA Section 204(j).” Both you and the new employer sign it.⁴

When to File

USCIS accepts Supplement J in three situations:

Proactively, when you’ve received a new permanent job offer in the same or similar classification and want to notify USCIS before being asked.
In response to a Request for Evidence or Notice of Intent to Deny asking you to confirm that the job from the original I-140 (or a previously submitted Supplement J) is still available.
After the original employer withdraws the I-140 or goes out of business and USCIS issues a NOID.

In each situation, the I-485 must have been pending 180 days or more, or USCIS will reject the filing.²

What Goes on the Form

You provide your A-Number and your pending I-485 receipt number. The employer provides its Federal Employer Identification Number, business address, and a certification that the offered job is legitimate and permanent. The most important content is a detailed description of the new job duties. Include the percentage of time spent on each major function so the officer can compare the core work against the original petition.⁴

You are responsible for identifying the SOC code that best describes the new position. Use the Bureau of Labor Statistics database and match the code to what the job actually involves day-to-day, not to the most impressive-sounding title. A poorly chosen code creates avoidable problems.

After You File

USCIS issues Form I-797C, Notice of Action, as a receipt. Processing can stretch to several months or longer depending on workload. If USCIS needs more information, it issues a Request for Evidence. The standard response deadline for most form types is 84 calendar days from the date USCIS mails the RFE, with a 3-day mail buffer, so a response received within 87 days of the mailing date is considered timely. Missing the deadline can result in a decision based on what USCIS already has.⁵

If USCIS decides the new job is not in the same or similar occupational classification, it denies the Supplement J and the I-485 with it.¹ A failed portability request doesn’t just reset the job question; it can end the entire adjustment application.

Keeping Work Authorization During the Switch

Porting your green card petition does not, on its own, let you work for the new employer. You need independent work authorization to start the new job.

If you hold H-1B status, your new employer can file a new H-1B petition on your behalf. Under H-1B portability, you can begin working for the new employer as soon as that petition is filed, without waiting for approval, as long as the petition is nonfrivolous, is accompanied by an approved Labor Condition Application covering the work, and is filed before your current authorized stay expires.⁶

If you hold an Employment Authorization Document based on your pending I-485, you can generally use it to work for any U.S. employer. EADs are not tied to a specific employer, but they expire; if the EAD lapses, so does your ability to work, regardless of the portability request.

If the Old Employer Withdraws or USCIS Revokes the I-140

One of AC21’s central protections activates after the 180-day mark. If your former employer withdraws the I-140 after the petition has been approved for 180 days or more, or after your I-485 has been pending for 180 days or more, USCIS will not revoke the approval. The I-140 stays valid for portability and priority date retention, though USCIS treats the original job offer as withdrawn. You then need a new qualifying job offer to port to under INA 204(j), or a new I-140 filed on your behalf, to keep moving toward permanent residence.⁷

Fraud-based revocation is different. If USCIS seeks to revoke an approved I-140 based on fraud or willful misrepresentation, it must issue a Notice of Intent to Revoke. Under the policy adopted from Matter of V-S-G- Inc., beneficiaries who have properly ported are considered “affected parties” and must receive notice. That gives you standing to submit rebuttal evidence and, if necessary, file an appeal on Form I-290B, a right beneficiaries don’t normally have in I-140 proceedings.⁸

An employer withdrawal after 180 days is survivable. A fraud-based revocation threatens the entire application, though you at least get notice and a chance to respond.

Priority Date Retention

Your priority date, which sets your place in the visa queue, survives a job change under AC21. When an I-140 has been approved for 180 days or more, the priority date is retained even if the employer later withdraws the petition, and you can use it with a new I-140 filed by a different employer or with a portability request.¹ If the new job doesn’t meet the same-or-similar standard, you still keep the priority date, but you have to start a fresh I-140 and I-485 process to use it.

Practical Questions That Come Up

Gaps Between Jobs

AC21 doesn’t explicitly address unemployment gaps. Brief gaps are common and generally tolerable. Extended unemployment is a problem because you need a valid, bona fide job offer at the time USCIS finally adjudicates the I-485. If you’re unemployed when the decision is made, there may be no qualifying offer to support the application.

Porting More Than Once

Nothing in the statute or USCIS policy limits you to a single port. The new job offer can come from the original petitioning employer, from a new employer, or from a business you own.¹ Each port needs its own Supplement J, and each new position must independently satisfy the same-or-similar standard measured against the original petition, not against the most recent ported job.

The Intent Requirement

USCIS looks at whether the original I-140 represented genuinely intended employment when it was filed. Both the sponsoring employer and the beneficiary must have actually intended the job to happen. This tends to surface when someone ports very soon after filing the I-485, or when the porting destination is a business the applicant owns. If the pattern suggests the original petition was never meant to produce real employment, USCIS can deny the portability request on intent grounds alone.¹
