I became a US citizenship mostly because I always suspected there would come a time when I 'd want to live outside of the US, even temporarily, and I just didn't want to deal with re-entry permit or having to stress about coming back to the US every 6 or 12 months in order not to lose my residency. I wanted the freedom to come and go as I pleased, and at the same time, not burn any bridges.
I am glad I did as after 10 years in the US, I am now seriously thinking about leaving the US and going back to Europe, and will try to do so next year. Having a US passport provides me with the freedom to come back whenever I want (if I decide to). I'd say that's probably the main reason I became a US citizen.
In terms of benefits, I like to have the right to vote , but I would have never become a US citizen just for that benefit. I also always knew I'd have no interest in sitting on a jury or work for a federal agency, and I have another passport from a European country so traveling the world visa-free was never an issue, and it's obviously not an issue for you either, travelchick.
In any case, Travelchick, your reasons for being on the fence are valid. Personally, having US citizenship provides me a certain peace of mind , and I also think it's good to have options.
Edit: Just realized that the thread is a year-old, would want to know if the OP went through with the application.
