my grandmother was born american, and lived there until she was 9 (1940), then moved to canada. she obtained her american citizenship until about 15 years ago, when she became a full canadian citizen. my mother never bothered to become a dual citizen, though i think she could have. i am now looking to go to school in the states, and eventually live there permanently. since my grandmother was once considered an american citizen, would it be relatively easy for her to obtain dual citizenship now? if she did, would my mother and i then be able to?
