I am Canadian. become US resident from Sep 2022 (CR1) and haven't worked on US soil in 2022.
I called my accountant and she said I dont need to because I had not worked in states yet and been here less than 6 months. So she is suggesting file separately and let me file mine in Canada for 2022. And from 2023, I can file for full year.
I thought I still have to file $0 in US by law. But the accountant seemed confident that I don't need to. So just here for second opinion.
Thanks,
