I am a recent Ph.D. graduate and now I am a postdoc working under OPT with F1 visa. I have been living in the US for more than 10 years. I got married in Feb 2018. However, last year, I filed tax as a single. This time I have been trying to file tax as married. However, my wife is under F2 visa and she was in the US for about 6 months in 2019. She does not have SSN or ITIN. Under F2, she can't work so she is dependent on me. After completing my postdoc, I moved to a different state in the mid-Oct 2019. So this means I need to file taxes in two states. What is the correct way to file tax under my situation? Should I file as MFJ or MFS? Do I have to post W-7 to IRS as well as both the state tax office?
As a postdoc, I get paid a low salary to afford the paid tax services. So, I am trying to file tax on my own. I would highly appreciate any help.
