to file 1040 or 1040NR
Hi,
I came to the US as a student under F1 visa in August 2014. After graduation in May 2018, worked on OTP under F1 visa till November 2019, after which switched to H1B. I was present in US till March 2020 after which left for India. Now, for my 2020 tax return do I file under 1040 or 1040NR?
Thanks!
