Adjustment of Status - I-485

I met my wife on Facebook we talked and got to know eachother for a year, started dating shortly after that then dated for a year and half and got married. It was a small court wedding with just her brother and my sister as witnesses. My parents stay overseas so couldn’t make it. We filed this December after 2 years of dating. We sent affidavit from friends and her whole family. We have a joint account for about a year now, she’s on my car insurance. We are about to file taxes together, we have 2 plus years worth of pictures. The only thing is we don’t live together as she stays in another state due to school she’ll be graduating in a semester then she’ll move to my state with me. We sent her class schedule to back it up and was honest about us not living together. For the past 2 and half years we try to see eachother every month or so. We take trips together with friends and family. We sent all the flight tickets, hotel reservation Airbnb. Birthday pictures and everything. My parents came this year and met her parents, we all took pictures and had a bbq. My question is will us not living together be a problem? And I just received a courtesy letter for my medical. How long should I expect my interview and what other documents can I get? My timeline as shown
