Job portability after 180 days: what AC21 actually allows

Portability matters to people whose green card depends on an employer. If an adjustment application has been pending 180 days or more, a new job in the same or a similar occupational classification can keep the underlying petition valid rather than sending you back to the start.

The baseline requirement

Before portability, the ordinary rule:

"An alien who has a pending application to adjust status to that of a lawful permanent resident based on an approved employment-based immigrant visa petition filed under section 204(a)(1)(F) of the Act on the applicant's behalf must have a valid offer of employment based on a valid petition at the time the application to adjust status is filed and at the time the alien's application to adjust status is adjudicated, and the applicant must intend to accept such offer of employment." 8 CFR 245.25(a)

That is the dependency. The offer has to be live at filing and still live at adjudication, which in a backlogged category can be years apart.

What portability changes

"Under section 204(j) of the Act, the applicant has a new offer of employment from the petitioning employer or a different U.S. employer, or a new offer based on self-employment, in the same or a similar occupational classification as the employment offered under the qualifying petition, provided that: (i) The alien's application to adjust status based on a qualifying petition has been pending for 180 days or more" 8 CFR 245.25(a)(2)

Three destinations are named: the same employer in a new role, a different US employer, or self-employment. The constraint is the occupational classification, not the identity of the employer.

The remaining conditions in the regulation are that the qualifying petition "has already been approved", or is pending when the beneficiary notifies USCIS of a new job offer 180 days or more after the adjustment application was filed and is subsequently approved, and that "the approval of the qualifying petition has not been revoked."

The regulation also requires intent on both sides: "the applicant and his or her intended employer must demonstrate the intention for the applicant to be employed under the continuing or new employment offer (including self-employment)".

How it is evidenced

USCIS may require, or the applicant may volunteer, a demonstration "on Form I-485 Supplement J, with any supporting material and credible documentary evidence, in accordance with the form instructions" that either the original offer is continuing or the portability conditions are met.

Two practical points follow. The form instructions govern the detail, and they change, so work from the current version rather than from a description of it. And "credible documentary evidence" means the job offer needs the same documentary discipline as anything else in an immigration file.

Whether a specific new role is in the same or a similar occupational classification is a legal judgement that turns on the facts of both jobs. It is not something to decide from an article, and getting it wrong has consequences for a pending application.

Why this is mostly not an EB-1A problem

The dependency portability exists to solve is the job offer. EB-1A does not have one:

The regulation provides that "Neither an offer for employment in the United States nor a labor certification is required for this classification", and that anyone including the person themselves may file. That is covered in the two requirements that are not about your evidence, which explains what EB-1A asks for instead: clear evidence you are coming to continue work in your area of expertise.

The same is true of the national interest waiver, where the waiver is precisely of the job offer requirement. The NIW three prongs covers that.

So the practical comparison is this. On EB-1B or EB-1C, your green card is tied to an employer relationship and portability is the mechanism that loosens it after 180 days. On EB-1A or NIW, that tie never forms. The three EB-1 classifications compared sets out which is which.

Where it intersects with revocation

The two rules are written to work together. The revocation regulation says that where an employment-based petition is withdrawn, "the job offer of the petitioning employer is rescinded and the alien must obtain a new employment-based preference petition in order to seek adjustment of status or issuance of an immigrant visa as an employment-based immigrant, unless eligible for adjustment of status under section 204(j) of the Act and in accordance with 8 CFR 245.25."

The same carve-out appears for the case where the petitioning employer's business terminates. What can revoke an approved I-140 covers both, including the 180-day thresholds that decide whether an approval survives.
