Thank you! So, to clarify: IF I already passed the substantial presence test under my h1b status this year (i.e. 31 days during this year, and 183 days in the three year period - as you described), THEN I can file as a resident for tax purposes? And NOT as a dual status alien?
So I didn't automatically turn into a non-resident for tax purposes in 2021 just because I switched to F1 status (because I passed the substantial presence test from h1b status)?
