Hello guys, so I have been having a long distance relationship with a girl for about 3 years (it was long distance since ive been active duty in the Marine Corps). She lives in the US, and her father is here on an E2 visa. She is here on a dependant visa. She turns 21 in May of 2022, and I am planning on marrying her before her visa expires. We plan on getting married in a court house since I do not have much money.
What is the process of getting her a green card? What exactly do i have to do? What does she have to do? Can you list it step by step please
Edit: I am assuming I will need a lawyer?
