My mother was born in New Brunswick in 1940, and lived in Canada until 1964, when she married a US citizen and moved to the U.S. and had me (also in 1964). She became a naturalized US citizen in the mid 1990's (I believe she is now a dual citizen). Am I a citizen? I know there are a lot of factors (she was born before 1947, she's my mother instead of father, I was born in U.S., etc) and that there have been changes in the law. Can someone help me? I have the application and know I can send it in for a definitive answer. However, I live near the U.S.-Canadian border (U.S. side), and would like to start planning to move. Having an idea would let me know whether it would be worth it to get a shorter 6-month lease and pay more each month. I would much prefer to live in Canada and commute to the U.S. for work (I think I understand the tax implications).
