I am a US Citizen, my husband is a permanent resident whose green card expires in Nov. 09. Does it automatically get renewed or am I required to sign something? And what happens if I am contemplating a divorce. Does he get deported?
If he has a "permanent green card," divorce has no impact on it and renewal is a minor process in which your signature is not needed. If he has a conditional green card, he is required to file Form I-751 (read the instructions), where if the marriage was entered into in good faith, he can obtain his permanent green card even without your signatures.
