What's the fastest way to get my gf US citizenship ? My gf lives in the UK and I'm in the US she wants to come live with me. Problem is we're both pretty broke at the moment, corona virus closed my job so I'm getting a new job soon. 

Anyway it's best for her situation that she gets here as soon as possible. She's not happy where she is and no place to go or stay. 

So what's the fastest way i can get her here ?
