I came to US in August 2015 on F1. I got a full time job after graduating and was on F1 OPT from 2016. I changed my status to H1B on May 1st, 2019. Until last year I had been filing 1040 NR. How do I file my taxes this year ? Also for the substantial Presence test SPT, should the current year be 2019 (current tax year) or 2020 ? Please advice.
