Keeping your priority date when the petition or the job changes

Three different things people call portability

The word is used for three rules that sit in different parts of USCIS guidance and protect different things. The first keeps a priority date from one approved petition to another. The second keeps an approved petition alive when the employer withdraws it late. The third, created by the American Competitiveness in the Twenty-First Century Act and known as AC21, lets a pending green card case follow a worker to a new job. A person can rely on one, two or all three over the life of a case, and mixing them up is the most common reason for a wrong assumption.

Rule one: the date follows the approved petition

The USCIS Policy Manual says that once a petition is approved, the beneficiary keeps the priority date set when the labor certification was filed, and can use it on later petitions. Its example is a worker who uses the earlier date to apply under EB-1 or EB-2. The new employer, the new job and the new category can all differ; what travels is the place in line. The date stays behind in three cases only:

• USCIS revokes the earlier approval because of fraud or willful misrepresentation;
• the Department of Labor revokes the labor certification;
• USCIS finds that the earlier approval was based on a material error.

Nothing in that rule requires the first employer’s cooperation, and nothing requires the first job to still exist. That is what makes it valuable: a worker who leaves a company years after the first I-140 was approved does not go back to the end of the queue.

Rule two: withdrawal after 180 days

Employers withdraw petitions when a worker leaves or a business changes. The USCIS page on I-140 procedures sets the line at 180 days: if the petitioner asks to withdraw an I-140 that has been approved for at least 180 days, or the related Form I-485 has been pending for 180 days or more, USCIS does not revoke the approval and the beneficiary keeps the priority date. The job offer is treated as withdrawn, so the petition no longer supports a green card on its own, but it stays approved for job portability unless USCIS revokes it on other grounds. Before that mark, a withdrawal can cost the approval.

Rule three: AC21 and a new job while the I-485 is pending

The Policy Manual chapter on job portability lets an applicant change employers without a new petition when four conditions meet:

• the I-485 has been pending with USCIS for 180 days or more when USCIS receives the request to port;
• the applicant is the beneficiary of an approved I-140, or of a pending one that is ultimately approved;
• the new job is in the same or a similar occupational classification, judged on all the circumstances, with occupation codes as a help but not the answer;
• the new offer is documented on Form I-485 Supplement J, required for requests made on or after January 17, 2017.

An applicant who ports this way keeps the priority date of the underlying petition. The count of 180 days starts on the filing date of the I-485, which is one more reason the month in which USCIS accepts the Dates for Filing chart matters so much for employment cases.

A voice in revocation proceedings

Workers often ask whether they have any say when an approved I-140 is threatened. The same USCIS procedures page gives them one in a defined case: a beneficiary whose I-485, filed on the basis of a valid I-140, has been pending for 180 days or more, and whose request to port to a new job USCIS has approved, can receive the notices in revocation proceedings and can file a motion or an appeal. The 180-day mark therefore does more than open the way to a job change. It also decides whether the person whose priority date is at stake can answer a notice that threatens it.

Putting the three clocks on one timeline

Picture a worker whose first I-140 is approved in year one. From that day, rule one protects the priority date on any later EB-1, EB-2 or EB-3 petition, barring fraud, a revoked labor certification or a material error. One hundred and eighty days after the approval, rule two starts to shield the petition against a withdrawal by the employer. If the worker files an I-485 when the filing chart allows it, a third clock starts on the filing date, and 180 days later AC21 opens the door to a move to a similar job with Supplement J. Each clock runs on its own; one being complete says nothing about the others.

What a kept date is worth, case by case

The value of portability depends on the queue you are in. The table takes one example, a priority date of April 1, 2015 from a first approved I-140, and places it in each employment category for a person born in India and for one born in mainland China, using the October 2026 Final Action Dates.

For an Indian applicant the stakes are plain. The Indian EB-2 cutoff, November 1, 2013, is about 11.2 years behind the worldwide date of January 1, 2025. Starting over with a new priority date today would mean joining the end of that line, while a kept date from an approval years ago may already be close to the front. The USCIS page on visa availability is a reminder of why: the country of chargeability, usually the country of birth, decides which column applies, and the per-country limit is what makes the Indian and Chinese columns long.

Where people lose the date by mistake

Most lost dates come from timing rather than law. A first I-140 that was never approved sets no retained date. A petition withdrawn in its first 180 days, with no I-485 pending that long, can lose its approval. A new job outside the same or a similar occupation does not qualify for AC21 even though the priority date itself may still carry over to a fresh petition. Keep every approval notice for Form I-140: the notice is where the priority date is printed, so a copy belongs in your own records and not only in the employer’s files. When the history includes a revocation, a denial or a change of category, an immigration attorney or a DOJ-accredited representative should read the file before anything is filed.
