Does anyone from India, Pakistan, or any other commonwealth country Canada PR holder have had any experience getting a F1/B1/B2/H1 visa stamp in Toronto.

If so can you please either post your experience here (like questions asked, documents that might be useful to take along)

Also how long is it taking these days inorder get the visa stamp?

I have been told it could take upto 60 days but i have heard of some people getting it the next day.

How do we know when the next available appointment from Visa Appointment Reservation System? ( https://www.nvars.com/use/ )

I appreciate your input.
