F-1 OPT → TN Change of Status Shortly After Reentering the U.S. — Does the 90-Day Rule Apply?

Hi everyone, I’m currently in F-1 status on OPT, which is valid until July 11, 2027.

I have a temporary trip to Mexico planned for December 5–11, 2026. I will return to the U.S. on December 11 and continue working on my F-1 OPT.

My employer is planning to file an I-129 in January 2027 to request a change of status from F-1 OPT to TN.

I want to clarify something specifically about the 90-day rule/misrepresentation guidance.

I understand that the 90-day rule is often discussed in the context of someone entering the U.S. as a nonimmigrant and then doing something inconsistent with the stated purpose of their entry, particularly applying for a green card/adjustment of status shortly after entering.

In my case, I would not be applying for a green card or immigrant status. I would be changing from one nonimmigrant status (F-1) to another nonimmigrant status (TN).

My timeline would be:

- Dec. 5: Travel from U.S. to Mexico

- Dec. 11: Return to U.S. in F-1/OPT status

- January: Employer files I-129 for F-1 → TN change of status

- I will not travel internationally after the I-129 is filed while the change-of-status request is pending.

Would filing the TN change of status in January, only a few weeks after returning from Mexico, raise any issue under the 90-day rule or create a presumption that I misrepresented my intent when I entered the U.S. on December 11?

I’m specifically asking about the 90-day/misrepresentation issue, not the separate issue of traveling while a change-of-status I-129 is pending.
