My friend is planning to go to Toronto US embassy for his H1b/H4 stamping along with his wife and two kids (under 18yrs). He requires Canadian visa. The concern he has as he plans to go in-person (for a quick turn around) is, does he have to take his wife and kids along with him to Canadian Embassy in NYC? His pay-stubs are good enough as proof of funds.
