Hi. I'm just trying to figure the process that I have to go through and my situation upon marrying a US Citizen. I'm extremely ignorant about the process, and tried searching the forum but I havent really been able to figure out the answers to my question.
So I'm getting married in less than a year, and just have a few questions.

I overstayed my visa as a child 15 years ago and have deferred action as of now. I'm a college student right now too.

1. Will I be able to travel once I get a green card?
2. How long would it usually take to get a green card, and would I have to live with my wife at the same address continuously for 3 years? We're in college so until later, it is impossible.
3. I would not have to leave the US at all, right? Just apply for the adjustment for status?

Any information about the general course, following my marriage will be really appreciated. Thank you guys so much!
