Should I get U.S. citizenship?
frossie: Absolutely yes - if you are a permanent resident and have held your green card for at least 5 years (the qualifying period) you should apply for citizenship. The reason is that a green card is not permanent; you lose it when you leave the country for a year or more. So if, for example, you got a consulting gig in Russia for a couple of years and then wanted to come back to the US, your previous green card would not be valid and you would have to start from scratch.If you can afford it, there is really no reason not to, even if you didn't have the additional complications with unclear other citizenships.The only people who should be careful about applying for US citizenship are those from countries (like Japan) who are barred from having dual citizenships; otherwise if you can afford it, it is frankly a no-brainer.Plus, if you are a citizen you can vote. I don't know about you, but living and paying taxes in a country where I don't have the right to vote kinda drives me crazy.I am not a lawyer, but look on the bright side, my opinion was free.
