Need advice!
I am foreign student in U.S.A. who got F-1 status. And now I am going to visit Russia via Canada. I got Canadian multi entry tourist visa two days ago. I am planning to go to Canada for few days, then go to Russia for 2-3 weeks. Obviously, come back in the same way. Will I have any unpredictable problems with IO or something new. I think is a splendid idea. Any advice or suggestions will count. Thank you.
