you’re eligible after 3 years if you’re still married to the same person, 5 years if not married to the same person. count from the date of your approval till 3 or 5 years.

@Laura Gutierrez it doesn’t matter if you been here for a million years. the law is clear, you have to be a permanent resident(green card) for 3years if obtained by marriage and you still with the same person, 5 years if not obtained through marriage or with the same person initially married to. the only way to get it faster and skip those years is by joining the military

@Sal Sal can you join military with 2 years green card

Yes so far as you have a green card whether 2 years or 5 years you can join the military

@God is,good yes you can, you can join the national guard and after ur basic training that last for 6 weeks, sign ur contract and apply for citizenship
