Dual citizenship and social security
- Does anyone know if the US makes you give up citizenship upon becoming
a Canadian citizen? I know that Canada allows dual citizenship, but
I'm not sure about the US. Also, if we have to give up US
citizenship, do we lose the right to collect US social security?
Also, keeping US citizenship obliges us to pay federal income tax on
any income over $70,000 (at least that was the cutoff a few years ago).
