I will be moving from US to Canada in Summer for 2 years. I was wondering if anyone has any tips when comes to collecting miles and points while I am there. I am wondering if I will be able to open similar cards in Canada which I have in US because they will be based on Canadian credit history, essential doubling my miles for each kind of card. That is obviously if those cards are offered in Candra e.g., United Explorer USA which I have and got 50K and United Explorer Canada which I could potentially get 50K. Will it also be beneficial to keep a US address ?

Sorry for the long open-ended question but I am really looking forward to some advice.

Thanks
