I have a friend that doesn’t have legal US documents, but who got married about a year ago to a US citizen. As far as I know, he hasn’t ever applied for a greed card or anything like that. Now that he is married, how could he safely go about getting a green card or getting residency? And does the fact that he’s married to a citizen speed up that process?
When you marry a US citizen you do not have to be placed on a waiting list for a green card, since you are an immediate relative of a citizen. That would speed it up in the sense that your application would not be on a waiting list, but it still has to be reviewed.
