Address cahnge
It would be better if you change the address before you move(means rightaway). The better way to change the address is call the IIO and do the address change. Also, when you\'re going for the PP stamping, you can give your new address there itself. Also, you can use form AR-11(from ins.gov site), which is very slow. Once you change, it would be better to check with the INS whether they updated your address(around after 15-20 days).
In this forum, I have seen different opinions of whether the USPS is forwarding the INS mails(some say yes, some say no, ofcourse from their personal experiences), so I am not sure, when the INS sends the cards to your old address what will happen.
Hope this helps.
