H4 to F1 Visa in Toronto Consulate

Hello everyone, I am presently on H1 and my visa was extended until 10/31/2021, my spouse is on H4 and got her approval.

Both of our visa haven’t been stamped, she is planning to covert to F1 visa.

Please advise whether going to Toronto is a good option and what happens if the visa gets rejected , can she book another slot and get her H4 stamping done or return to India to get the stamping ?

Please advise.

You can go to Canada for F1 stamping.

She can apply for H4 visa in Canada itself if F1 is denied.
