as for 1st and 2nd generations here, always good to have that dual citizenship in your pocket, so keep those passports current!
Wow! I am amused at all this talk as though US is going to go up in flames or sink underwater! Hey, some people came here without even being sure that they can find food to eat (the very first attempt at settling here ended in starvation and death by winter). Now you have McDonalds selling burgers for 29 cents every 2 miles. How bad can it get in your lifetime for anyone to think of emigrating?
