Thanks for reply. Unfortunately, it did not help my original questions.
I am still looking for help for my questions:
1. Before our marriage, my girlfriend (now my wife) lived in my house (I owned) for three years, after marriage, my wife lived in the house for one year. Does that three years (my wife lived as my girlfriend before the marriage) can be counted for the purpose of the at least of two years resident requirement?
2. Although we file the joint return for 2020, but my wife does not have the green card and still in applying process, can we both claim the $500,000 principal residence exemption even my wife does not have the green card yet?
Thank you.
