On Form I-129, the petition for a nonimmigrant worker, a "change of status" asks USCIS to change the worker's status while the worker stays in the United States. "Consular notification" asks USCIS to notify a U.S. consulate or port of entry so the worker can seek a visa or admission from abroad. They are two different choices in Part 2 of the form, and the form's instructions say to choose only one. This article explains the difference using the official Form I-129 instructions and the regulations.
What the Form I-129 instructions say about each choice
In the instructions, the "Requested Action" item lists several choices and says "Choose only one action." Two of them matter here.
- Notify the office in Part 4. The instructions describe this as: "Notify the office listed in Part 4. so the beneficiary(ies) can seek a visa or admission." It is for a beneficiary (the worker named in the petition) who is outside the United States, or who is in the United States but will leave to get a visa or admission abroad.
- Change the status and extend the stay. The instructions describe this as: "Change the status and extend the stay of beneficiaries who are now in the United States in another status." It is for a worker who is in the United States in a different nonimmigrant classification and is applying to change to a new one.
The instructions also list a separate choice to extend the stay of a beneficiary who already holds the status, and one to amend the stay. Those are not changes of status, because the worker stays in the same classification.
Who can ask for a change of status
The regulation on changing nonimmigrant classification, 8 CFR 248.1(a), says a person lawfully admitted as a nonimmigrant "who is continuing to maintain his or her nonimmigrant status, may apply to have his or her nonimmigrant classification" changed, with some listed exceptions. Whether a particular worker qualifies depends on that worker's facts, and an immigration attorney is the right person to ask.
What happens if you leave the U.S. while a change of status is pending
The regulation is direct: "If an alien timely files an application to change to another nonimmigrant status but departs the United States while the application is pending, USCIS will consider the change of status application abandoned." (8 CFR 248.1(f).)
That is the rule we can confirm in current regulation text. This article does not go beyond it. For example, we do not describe what a notice looks like if a petition is approved after the worker has left, because the USCIS pages that discuss it are marked archived and out of date. A person planning a trip while a change of status is pending should ask an immigration attorney first.
What this article does not cover
We do not state whether a pending change of status gives a worker lawful status, work permission in a new job, or protection from unlawful presence while it is pending. The USCIS pages we found on those points are marked archived. Ask the employer's attorney, and check the current USCIS pages linked below.
We also do not state the date a changed status begins. For cap-subject H-1B petitions, USCIS says a petition must indicate a start date of Oct. 1 or later of the applicable fiscal year, but that is a requirement for the requested start date, not a statement about when a change of status takes effect in every case.
Where this fits with the rest of the H-1B process
Both choices are made on the same form, so which one your employer selects depends on whether you are in the United States and what your plans are. If you want to understand the rest of the cap process first, see our guide on what happens after an H-1B registration is selected. For dependents, the Form I-129 instructions say dependent family members should use Form I-539 to file for an extension of stay; our Form I-539 page has the basics.
Recent H-1B developments worth knowing about
USCIS's H-1B page also describes an additional payment requirement that applies to certain H-1B petitions, and court orders about it. That requirement has changed more than once, so this article does not summarize it. Whether it applies to a particular petition is a question for the employer and its attorney. Read the USCIS H-1B page for the current state.
USCIS also publishes updates to the fees and the edition of Form I-129. We do not list fee amounts here. See the Form I-129 page and the fee schedule for the current edition and fees.
Common questions
Can both be requested on one petition?
The instructions say "Choose only one action" for that item.
Does traveling cancel a change of status?
Under 8 CFR 248.1(f), if you depart while a timely filed change of status application is pending, USCIS will consider that application abandoned.
Is a change of status the same as an extension?
No. The instructions treat extending the stay of someone who already holds the status as a separate choice from changing to a new status.
