Hi @pk, you are 99% correct in all you say.
a) all correct
b) I wasn't exempt, I was paying taxes (or getting a refund, it depended each year) since 2014, using the 1040NR
c) all correct
The adjustment to H1B was done in 2019, and there was an absence of three months after my F1 and before the H1B. I used Sprintax for my 2019 return. My husband was also a NR alien. Our country does not have an agreement of any sort for tax purposes with the US.
Thank you very much for your reply. I do understand the "convenience" aspect you mention, but from what I had read, if you had filed as non resident in 2019, you did not qualify. I will call the IRS and report back.
