I got a couple of answers regarding my question. But there is still no a consensus between the answers. So I would like to ask this question here again.
My time in the U.S. is as follows:
2015: J1 short-term scholar visa (visiting research in the U.S. for five weeks)
After that, I left the US. And I started to study in the U.S. from 2019.
2019: F1 visa (a MA in US)
2020: F1 visa (a MA in US)
2021: F1 visa (a PhD in US)
2022: F1 visa (a PhD in US)
2023: F1 visa (a PhD in US)
Given this, do you think my tax status in 2023 is resident alien? Thank you for your time!
