Changing Jobs After Your I-485 Hits 180 Days: AC21 Portability, the 485J and 3 Real Cases

The short answer: Changing jobs after your I-485 has been pending for 180 days is still allowed. The law has not changed, and this path still works in 2026. The employment-based immigration statute (INA 204(j), commonly called AC21) spells it out: once your I-485 has been with USCIS for 180 days and your I-140 (the immigrant petition your employer filed for you) has been approved, you can move to a "same or similar" job without redoing PERM (labor certification) or the I-140. Your new employer just signs a 485J (Supplement J to Form I-485). What has changed since policy tightened is how closely cases are reviewed: more people are being asked to submit a 485J, and interviewing officers press on whether the old and new jobs are really the same kind of work. The three things to watch out for: a 485J filed before the 180 days are up will simply be rejected, a new job that is too different from the original one, and signing a 485J for a job you don't actually plan to take.

When does the 180-day clock start? Can I switch before 180 days?

The count starts on your I-485 receipt date and runs until the day USCIS receives your job-change request. The USCIS Policy Manual says the count begins on the day the I-485 was properly filed and includes every calendar day until USCIS receives your portability (change-of-employer) request, as long as the I-485 has not been decided in the meantime.

The Supplement J instructions put it more bluntly: a 485J used to port to a new employer that is filed before the I-485 has been pending for 180 days will be rejected.

So the line you often see on forums, "You can change jobs the day after filing your 485; the new company just has to wait until day 180 to file the 485J," is half right and half risky:

The right part: the law requires the I-485 to have been pending for 180 days, not that you stay at your original employer for 180 days
The risky part: if you leave early and USCIS sends a Request for Evidence before day 180 asking you to show that the original job is still available, you can't produce that, and you can't switch to the new job yet either. That leaves you in a very tough spot

There is one more condition: your I-140 must be approved. The Policy Manual says the I-140 has to be approved before USCIS will recognize your change of employer. If your I-140 is still pending, stay put for now.

What counts as a "same or similar" job?

This is where job changes most often go wrong, and it is the officer's favorite interview topic.

USCIS looks at the totality of the circumstances. The Policy Manual lists these factors:

The occupational codes DOL assigns to the two jobs (SOC codes)
Job duties and responsibilities
Job titles
Required skills, experience, education and training
Whether a specific license or certification is required
Wages

Two points many people don't realize:

A big pay difference does not mean the jobs aren't similar, and similar pay doesn't prove that they are. Wages are only one reference point
A promotion to manager is fine, as long as what you mainly manage is still the same kind of work you did before, or the people doing that kind of work

The Supplement J instructions also say USCIS will compare jobs using DOL's Occupational Outlook Handbook, O*NET and the SOC classification system, and applicants can use the same resources to show that the two jobs are similar. The most practical interview prep is to line up the duties of your old and new jobs side by side, item by item.

I'm EB1A (extraordinary ability) or NIW (national interest waiver). Do I need a 485J too?

No. The Supplement J instructions are clear: applicants for extraordinary ability (EB1A) and national interest waivers (NIW) do not need to file Supplement J, because neither category is tied to a specific job in the first place.

That means EB1A and NIW applicants who change jobs aren't bound by the "same or similar" rule. If you're in one of these categories and receive a notice asking for a 485J, USCIS most likely sent it in error, as in Case 3 below.

Three real cases

All of the following are firsthand accounts posted by the applicants themselves on a Chinese-language immigration forum. They are not verified decision records.

Case 1: Changed jobs and states; the officer kept asking whether he'd "changed occupations" (2020 to 2022)

Priority date July 2017. Downgraded from EB-2 (second preference, advanced-degree professionals) to EB-3 (third preference, professionals and skilled workers) and filed the I-485 in October 2020
Changed jobs in December 2021, moving to a different state at the same time, and filed a 485J
Interviewed in September 2022. He worked as a technical program manager (TPM), and his old and new companies made different kinds of products. The officer kept asking whether he had changed occupations
He explained that the core of the job is program management, whatever the product is. "I still don't know whether he really understood in the end"
The officer didn't approve on the spot, then sent a request for an updated medical exam. A week after he submitted it, his status showed card being produced

The takeaway: the officer cares about what you do every day, not what products the company makes. Explaining your duties clearly matters more than explaining the company's business.

Case 2: Got a 485J request before finding a new job (2025)

His I-485 had been pending for 390 days when his company announced layoffs for March. He took unpaid leave, pushing his separation date to June
In January, USCIS sent a Request for Evidence asking for a 485J to show the job was still available, due April 20. He didn't notice it until mid-March, leaving only 22 days
Forum members suggested "have a staffing firm sign a 485J first" or "start your own company and sign it yourself"
In the end his original employer agreed to sign the 485J, and he submitted it in early April
Approved on July 25

Read this outcome carefully: the approval came after his planned separation date. Supplement J asks the employer to confirm the job the applicant will take once approved. When the employer signed, it had already decided to lay him off. Whether that signature holds up legally is a question for a lawyer; it is not a playbook to copy. The real lesson of this case is a different one: read USCIS notices promptly. He lost almost two months of response time for nothing.

Case 3: EB1A applicant asked for a 485J; the request was withdrawn days later (2026)

EB1A, filed the I-485 in November 2025
On March 20, 2026, the case showed as actively under review, and the same day a Request for Evidence appeared in the online account asking for a 485J
The lawyer's advice: wait for the official paper notice before responding
On March 26, a text message arrived: RFE cancelled
Approved March 27; card production started April 2

EB1A never needed a 485J, so the notice was sent in error. The applicant himself said USCIS "really is a bit of an amateur operation." If you get an RFE that looks wrong, have a lawyer check it first. Don't rush to comply.

One case doesn't make a pattern. But taken together, the three show that in 2026, I-485 applicants do get asked for a 485J, and officers really do press on whether the old and new jobs are similar. Being prepared beats counting on luck.

Common claims online: which ones are wrong

"The 485-based EAD is only good for 180 days now, and it can't be automatically extended anymore." Half right.

No more automatic extensions: true. EAD renewals filed on or after October 30, 2025 no longer get the automatic 540-day extension. Once the card expires, you can't work until the new card is approved. See our article on this
"Only 180 days": false. A USCIS policy update on December 4, 2025 cut the maximum validity of EADs for pending I-485 applicants (category C9) from 5 years to 18 months. It applies to EAD applications pending on or after December 5, 2025, or filed after that date

This matters for job changes: if you work only on a 485-based EAD, file the renewal well before the card expires. Otherwise, if the new card isn't approved in time, you have to stop working.

"Once I switch jobs I can just work on my 485 EAD and drop the H-1B." Think this through.

An H-1B only lets you work for the employer that filed your H-1B. If you go to a company that hasn't filed an H-1B for you, you're working on your 485 EAD, and you are no longer maintaining H-1B status. That's fine if the I-485 gets approved. But if the I-485 is denied, you have no H-1B to fall back on. For this reason, many forum members and some company lawyers lean toward transferring the H-1B whenever possible and keeping the EAD as a backup. That's a cautious approach, not a legal requirement. Ask a lawyer which way to go.

"If I'm laid off with 60 days' notice under the WARN Act, I still count as employed during those 60 days." Most replies say yes, but confirm with a lawyer.

In March 2026, a laid-off engineer asked: his I-485 was a little over ten days short of 180 days, but the separation date in the company's paperwork was 60 days away. Did that satisfy the 180 days? Most forum replies said yes, and that the H-1B 60-day grace period also starts from the official separation date. The reasoning makes sense: during the notice period you are still on the company payroll. But no official USCIS document answers this directly. If you're in this situation, bring the company document showing your separation date to a lawyer. For how the grace period is calculated, see our article here.

The path not to take

Don't have someone sign a 485J for a job you don't plan to take.

Forum members keep suggesting: if you're laid off, get a staffing firm or a friend's company to sign a 485J, and sort things out after the green card is approved. Don't do this.

The Supplement J instructions are clear that the applicant is confirming a permanent, full-time job offer they intend to accept once approved. The Policy Manual also says the original job offer must be bona fide: the employer really intends to hire you, and you really intend to take the job. Signing for a job you don't intend to take is a misrepresentation to USCIS. Fraud or misrepresentation to obtain an immigration benefit is a separate ground of inadmissibility, and it has no time limit. Once you're found to have done it, the damage goes well beyond this one green card.

I changed job families before filing I-485. Can I still use the original PERM?

The current job title alone does not answer that. For a category that requires an employer job offer, the Supplement J instructions ask whether the job offered in the I-140 remains valid and whether you intend to take it when the I-485 is approved. USCIS says the basis is prospective work, not necessarily the job you currently hold. [1] If duties or employers have changed, ask the employer and immigration lawyer to review the original PERM, I-140, and offered job. A job change before filing I-485 is not automatically covered by the AC21 rule for changing jobs after the I-485 has been pending for at least 180 days. [2]

What to do now

If you haven't changed jobs yet:

Look up your I-485 receipt date in your USCIS online account and work out exactly when day 180 falls
Confirm your I-140 is approved
Compare the new job description line by line against the duties in your original PERM and I-140, and think ahead about how to explain any big differences
Confirm the new company is willing to sign Supplement J (the new company's lawyer will usually judge whether the job is similar)

If you've already changed jobs:

After day 180, you can file the 485J proactively or wait until USCIS asks for it. The USCIS instructions accept either
Bring the 485J signed by your new company and the job description to your interview
If you're working on a 485 EAD, keep a close eye on the expiration date and file the renewal early

If you've received a request for a 485J:

Check the deadline right away. Don't let it slide down to 22 days like in Case 2
If you're EB1A or NIW, have a lawyer check first whether it was sent in error
If your original employer is still willing and you plan to stay, ask them to sign; if you've already changed jobs, ask your new employer to sign

If you're waiting on a green card, you may also want to check this month's visa bulletin, what happens after you file your I-485, or use our case status tracker to keep an eye on your case.

This article is not a substitute for a lawyer. Be sure to talk to one if: your new job's duties are clearly different from the original (for example, moving from engineering to product, or from technical work to sales), your I-140 isn't approved yet, you've received an RFE or Notice of Intent to Deny (NOID) about your job, you're being laid off, or your employer has withdrawn your I-140.
