My green card was approved on june 15th 2002 in California, I did my stamping on June 20th 2002. But two months back I moved to St Louis, MO. I'm planning to go to India after two weeks. Where should I go for re-stamping my passport. Can I go to local St Louis INS office?. Also how early can I go for restamping, can I go two months early befor the expiry, will they re-stamp my passport .
Thanks for your help.
