Student Traveling

[Fess]

Hello,

I'm attending school in canada. I'm Norwegian from Nowway. there is a sticked visa in my passport with the validity and with a multiple entry line.

On the board, I have a study permit, stapled to the passort saying authorized for re-entry.

So I dont know wheather I can leave and come back or not.

I'd like to go to Washington in the U.S. to visit me friends for Xmas,  do I ask the goverment for a multiple enrty licence or permit or whatever its called? :?:

Thank You
