Water wilderness for internationals.

Hello all,

I have been accepted at the water wilderness program but I am a bit concerned about the Canadian visa. I have not yet received my US visa yet and am in process of applying. To attend the water wilderness I will have to apply for a Canadian visa as well so when should I expect to arrive at the USA to process for the Canadian visa? Any international student with prior water wilderness experience here? It would be great help if you could guide me through.

Thanks!
