What are the benefits of dual citizenship? Besides the healthcare
I can't speak for any other countries, but I want dual citizenship so I can work here without having to constantly go through the hassle of getting work papers. Other than that I don't know of any benefit of having dual citizenship.
I no longer have health care available in Canada - it is only available to residents and this goes back to my comment about residency. I am citizen of Canada, but a resident of no country. Weird, eh? There is a small fee, maybe $50 a month, to keep your health care active so although I still have my card it wouldn't work, like an expired credit card.
As for taxes, there is a reciprocal agreement between Canada and the US so that you only pay taxes in one country. Both countries base where you pay your taxes on based on residency so I pay here in the US. Yes, I know I just said I wasn't a resident of any country, but for tax purposes I'm a US resident.
I travel on a Canadian passport and Lex will have both a Canadian and US passport. Unless we are travelling to Canada he will use a Canadian passport.
Also, right now I can't vote either in Canada or US since I am not a resident of Canada, but I a a citizen. Once I have dual citizenship I can vote wherever I am a resident.
I think that's about it.
My Stepfather was Canadian, so when I was 10 I got my landed immigrancy then had to take the test in high school to get my dual citizenship.
Ah yes, I wouldn't know anything about the rules as they pertain to adoption.
