I am in the US with an approved COS from B2 to F1, so my F1 visa is yet to be stamped on my (Indian)Passport.
1. My STEM masters program is for 9 months, and my I20 has a start and end date of 2 years(2026). Do I have to stamp before the end of 2 years to avail myself of the OPT and STEM validity?
2.I might have to visit a family member in Canada sometime in mid-2025 after my master's program has started. Is it advisable to go to Canada since I do not have the F1 stamped on my Visa? If I can visit, then will I require a different visa?
3. Is it possible for me to schedule my F1 Visa stamping in Canada during the visit? Or would you advise something different here? Or is it better to get it stamped in Mexico?
If you are on an F-1 visa converted from B-2, your visa stamp is only necessary if you plan to travel outside the U.S. While in the U.S., your status is governed by your I-94, which typically says "DS" (duration of status) and remains valid as long as you maintain your student status.
If traveling briefly to Canada or Mexico for under 30 days, you can use Automatic Visa Revalidation (AVR) to return without a visa stamp, provided you haven’t applied for and been refused a visa during your visit. Scheduling visa stamping in Canada is risky—if denied, you lose AVR eligibility and must return to India to reapply.
Trying to get an F-1 while an AOS/I-485 is pending has been a recurring theme in our community. Last year in May/June we had spent two hours talking about this theme in our community conference calls. A lot of people wanted to do their MBA and were not able to wait for their green cards to join school.
Generally speaking when you have exhibited immigrant intent, getting an F-1 becomes difficult. On top of that, USCIS has said that F-1 is not compatible with a simultaneous I-485. But USCIS has never told us what happens if do file for an F-1 while an I-485 is pending.
