I'm an 18 year old Mexican Guy who is dating this amazing beautiful white girl. We been dating for a whwhile now. She said she wants to marry me.

I'm Mexican, 18 year old. Living in united states. I came here wwith a visa. as a child. It expired like not too long ago. I didn't realize it, if I had realized it I would of try taken a citizenship. but parents didn't let me know. So basically I'm currently living as an illegal immigrant. I have a job I go to school and no criminal record. First question what can I possibly do to gain residency by myself.

Me and girlfriend want to gget married when she graduates college. That's like 4 years from now. I love her. She loves me. If we get married, whatber do i nneed or how it happens?

Or is there something I don't know

?
