F Visa

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?

I was on H1B (shows automatically revoked), then switched to B2, then switched to F1 (current status) without leaving the US.

1 - Will automatic revocation of H1B cause any issues? Is it simply because the employer has submitted a withdrawal after terminating my role?

2 - When I find a new job that sponsors, will the revoked H1B cause any issues? I have only used 4 months of my initial H1B. It will be a switch from F1 to H1B if everything works out.

Just wanted to clarify what "Case Was Automatically Revoked" means; revoked - sounds a bit concerning. My role was terminated.

- H1B 60-day grace period starts on the date of getting notice of layoff from the employer, on the date of the severance paycheck, or on the last date of the regular paycheck?

- During H1B 60-day grace period, what is the best time to apply for B1/B2? When 30 days are left, 15 days are left, etc.?

- H1B is for 6-years of work, or 6-years total? I mean does unemployment time or B1/B2 time etc. also counts in 6-years of H1B?

- After layoff on H1B, if decided to go to school, then how to stay in US until getting admission decision and until school starts, that could take many months.

- After layoff on H1B, what is the better option to choose between B1/B2 and F-1?
