I first came to the US in 2014 as F1 student for a few weeks, no income.
Returned in 2017 as F1 and received income from 2017~2021.
I had campus stipend from Jan~March in 2021. According to Glacier my "Residency status change date: 7/3/21 to resident alien" & "Residency status start date: 1/1/21 to resident alien". Springtax also said I am a RA. However, I failed to finish my degree in Jun 2021 and became out of status, left US in mid Dec 21
1. Can I file my 2021 tax return as dual status? I complied with visa requirements when receiving stipend, so RA for the first 5.5 months of 2021. And became NRA from mid June when I became out of status?
2. Or am I NRA for the entire 2021? Since I fail to maintain visa status to reach 7/3 and didn't stay in US for the entire 2021 and none in 20222.
