@Opus 17 I just noticed this issue recently and haven't filed any 1040X, sorry if I didn't make it clear.
@pk Regarding your description:
a) True.
b) I left the U.S. on April 7, 2022, to do my PhD research in other countries, so I am still a PhD student at IUB but just not physically present in the U.S.
c) I do have U.S. bank accounts. I stayed in my home country (Taiwan) for a year and then relocated to Switzerland to date. Yes, I am still NRA.
