Can I Switch Jobs After I-140 Approval? AC21 and the 180-Day Rule

Yes, you can switch jobs after an I-140 approval, and how you do it depends on one date: whether your I-485 adjustment of status application has been pending for 180 days. Past that mark, federal law lets you move to a new employer in the same or a similar occupation without restarting the green card process. Before that mark, your new employer generally has to file a fresh petition, but you keep the priority date your approved I-140 gave you. Everything else about a job change during the green card process flows from which side of that line you’re on.

The 180-Day Portability Rule

The American Competitiveness in the Twenty-First Century Act of 2000 (AC21) added Section 204(j) to the Immigration and Nationality Act. It states that an employment-based immigrant petition “shall remain valid with respect to a new job if the individual changes jobs or employers if the new job is in the same or a similar occupational classification as the job for which the petition was filed.”¹

Two conditions have to be met before you can use it:

Your I-140 must be approved (or approvable in certain withdrawal scenarios).
Your I-485 must have been pending with USCIS for at least 180 days from the receipt date.²

Once both are true, you can port your green card application to a new employer without filing a new I-140. You carry your priority date, your pending I-485, and your place in the visa queue.

What “Same or Similar” Occupation Means

USCIS doesn’t apply a formula. Officers look at the totality of circumstances and compare the two positions across several factors:³

Job duties and day-to-day responsibilities.
Required skills, education, and training.
SOC codes from the Department of Labor’s Standard Occupational Classification system. Matching or closely related codes help, but they aren’t the sole deciding factor.
Wages. A pay difference alone won’t disqualify a position, since salaries vary by region and company. A large gap should come with an explanation.

A different job title doesn’t matter much on its own. What matters is whether the core nature of the work is substantially similar.

Promotions

Career progression is built into the analysis. A lateral move or a step up to a senior version of the same role generally fits within the same or similar classification. Moves into management are harder to predict but not automatically disqualifying. The USCIS policy manual gives the example of a software developer becoming a Computer and Information Systems Manager, which can qualify because the manager oversees people in the same occupational family.²

Relocating

Moving to a new city or state doesn’t block portability. USCIS acknowledges that geography drives pay, so a salary change from a low-cost to a high-cost area, or the reverse, isn’t a problem on its own. Self-employment in the same or a similar occupational classification is also recognized as a valid portability option.²

Filing Form I-485 Supplement J

You notify USCIS of the job change by filing Form I-485 Supplement J, “Confirmation of Valid Job Offer or Request for Job Portability Under INA Section 204(j).”⁴ You complete your portion, and the new employer completes sections describing the job duties, the offered wage, and the nature of the position.

USCIS will reject a Supplement J filed before your I-485 has been pending for 180 days. Once the 180-day threshold is met, you can start working for the new employer using your EAD or H-1B transfer, and the Supplement J should follow promptly. If USCIS reaches your I-485 without a Supplement J on file, expect a Request for Evidence, which adds processing time. USCIS may also request a Supplement J even when you haven’t changed jobs, simply to confirm the original offer is still valid.

If You Change Jobs Before the 180-Day Mark

If you haven’t filed your I-485 yet, or it’s been pending fewer than 180 days, AC21 portability isn’t available. Changing employers at this stage generally means your new employer starts fresh: a new PERM labor certification if the category requires one, and a new I-140.

You don’t lose your place in line. An approved I-140 in the EB-1, EB-2, or EB-3 category preserves your priority date for any future petition in those same categories, and if you end up with multiple approved petitions, you get the earliest priority date among them.⁵ One exception: if the original I-140 was revoked because of fraud or willful misrepresentation, the priority date from that petition is lost.⁶

Throughout the transition, you have to maintain valid nonimmigrant status. If you’re on H-1B, that means the new employer files an H-1B petition for you before you start work. Falling out of status can put the whole green card process at risk.

If Your Former Employer Withdraws the I-140

The timing of a withdrawal decides the outcome. If the employer requests withdrawal less than 180 days after the I-140 was approved, and your I-485 hasn’t been pending for 180 days either, USCIS automatically revokes the petition. But if the I-140 has been approved for 180 days or more, or a related I-485 has been pending for 180 days or more, the petition “remains approved unless its approval is revoked on other grounds.”⁷ The old employer’s job offer disappears, but the approved I-140 survives for priority date retention and portability.

The same logic applies if the company shuts down entirely. Termination inside the 180-day window revokes the petition; after it, the petition stays approved.⁷

The protection isn’t absolute. USCIS can still revoke an approved I-140 for fraud, willful misrepresentation, or invalidation of the underlying labor certification, no matter how much time has passed.

H-1B Extensions Past the Six-Year Limit

An approved I-140 matters even if your green card is years away. Under AC21 Section 104(c), H-1B workers with an approved I-140 who can’t file for adjustment because their priority date isn’t current can extend H-1B status past the six-year limit in increments of up to three years, renewable until a final decision on the adjustment application.⁸

This matters most for nationals of countries with long visa backlogs, where waits can run a decade or more. If you switch employers, the new employer can file an H-1B petition and use the previously approved I-140 as the basis for the three-year extension. H-1B is transferable to a new petitioning employer through a new I-129 filing.⁹ Changing jobs doesn’t cost you the extension as long as the I-140 remains approved.

What Happens to an H-4 Spouse’s EAD

If your spouse holds H-4 status, your approved I-140 can be the basis for their Employment Authorization Document under 8 CFR 214.2(h)(4). H-4 spouses can apply for an EAD when the principal H-1B holder either has an approved I-140 or has been granted H-1B status past the six-year limit under AC21.¹⁰ When you change employers, that eligibility generally continues as long as your I-140 stays approved and hasn’t been revoked for fraud or misrepresentation.

One recent change affects timing. As of October 30, 2025, USCIS ended the automatic extension of EADs for renewal applicants. H-4 EAD holders who file renewals on or after that date no longer receive an automatic extension while the renewal is pending.¹¹ If USCIS processing is slow, a gap in your spouse’s work authorization becomes a real risk, so plan the timing of a job change around the spouse’s renewal cycle.

Work Authorization During the Switch: EAD or H-1B

Once your I-485 is filed, you can apply for an EAD based on the pending adjustment application.¹² This EAD isn’t tied to a specific employer, which is what makes it useful for portability.

Relying only on the EAD has one risk worth understanding. If your I-485 is denied for any reason while you’re working on the EAD, there’s no underlying nonimmigrant status to fall back on. Keeping your H-1B active through the transfer, rather than dropping it in favor of the EAD, preserves valid work authorization even if the adjustment is denied. Some practitioners recommend that approach as a safety net during the early portability period.

A Note on Consular Processing

AC21 portability is written around the I-485 adjustment process, which happens inside the United States. The statute specifically references an application for adjustment of status “filed and remained unadjudicated for 180 days or more.”¹ If you’re getting your green card through consular processing at a U.S. embassy abroad and never filed an I-485, the standard portability provisions generally don’t apply the same way. Applicants who filed an I-485 and later switched to consular processing after the 180-day mark are uncommon, and the situation carries additional legal complexity that’s worth reviewing with counsel before you accept a new offer.
