customs and immigration, for the record

[gusl]

In Europe, customs is done at the final destination. This confused me. In Canada, USA and Brazil, it's done at the first place you land.

Immigration: arriving in Calgary, the officer asked why I renewed my visa in Seattle last month, and said that the study permit would have sufficed. This means that, as long as the Study Permit is valid, a valid visa isn't necessary to enter Canada!
