Hi! My husband came on a B2 visa. It expires in April and while we are trying to get everything filed before his stay expires in April we are having difficulty with getting his birth certificate so it might take longer than we hoped. My question is after his stay expires can we still file the AOS? If so, is he no longer subject to being deported once the application is received or since it was after his overstay will he be at risk until it is approved or denied? I am a US Citizen by birth. Thank you in advance!
