Thanks for your reply.
A) I entered with F1 in 2015, maintained my visa status until 2019, and changed to F2. Now, I'm preparing for the tax return for the income I earned in 2019 with STEM OPT. So, stayed as an F2 a long time ago does not change my current filing status? Some accountants say this rule applies to one's lifetime.
B) We married in our home country before coming to the US together. I worked with my OPT under the F-1 visa, and my spouse also found a school job during her first year as a graduate student, so we both have SSNs.
C) I think visa status and residential alien status for tax purposes are two different things, and I am now preparing for the 2019 tax, which I don't think is related to my current visa status. I understand that I cannot do anything with my F2 visa status, and I am complying with my status.
D) Please review again and share your thoughts about how I should file last year's return.
Thanks for your inputs.
