My 13 year old sister has a green card. My parents recently naturalized as US citizens and promptly applied for a US passport for my sister. They received the passport within a few weeks. Interestingly, the green card was also returned to us with the passport. Since she is a US citizen what should we do with the green card? Are we required to send it back to USCIS? Is there an well defined procedure for this?
Double post, already answered on a different thread. A bit off topic for this thread. I think you should have opened a new thread for this question.
