The Amazon Visa is best for foreign currency , when you travel but also if you buy anything from a US website . For everyday use , Tangerine Mastercard is gives 2 % on your select spending categories . You should also get the no fee SimplyCash Amex . What ' s good with Amex is that if you ever move to a different country they will transfer your credit history with them to the other country . They also have some of the best signup bonuses , so it would be good to build up some history with them if you feel like taking advantage of those cards with big signup bonuses in the future . I ' d say you should just get rid of old cards . It may damage your credit rating a bit but don ' t worry about micromanaging your credit rating unless you expect to be taking out a loan in the very near future .
