My son who was then 8 years old obtained a green card along with me & my husband. The green card expired early 2003. We are living in another country (outside theUS) since 1994 (the same year we received our greencard). My husband & myself has no interest in renewing our greencard nor staying in the US but my son who was a minor then but now an adult would like to live & work in the US. He made several trips in the US in the last couple of years and had difficulty entering the US. I think in the airport he was made to sign something before they allowed him to enter the US on his 2nd trip there last year. We still have our expired green card in our possession and from our understanding we have to return them to be destroyed, which we will gladly do on our next trip to the US. As for my son, given the length of the time that the green card is expired, can he still renew it? If so, how? Thank for your immediate response to this quiry.
