I arrived USA by fiance visa, I got green card. I had one son with the ex-husband.
After we married, my husband applied the petition for my son come to USA. Now my son moved to another place to live in my country, so "where I should send my document to inform for the change of his address, Nebraska or California Center??"
At first, we send petition to Nebraska, but now on the receipt sent back to us, they wrote the address is (from California):
US CITIZENSHIP & IMMIGRATION SVC
P.O. BOX 30111
LAGUNA NIGUEL CA 92607-0111
Please advise and Thank you.
