@bla_bla_123 ,
While your analysis is of the situation is generally correct, I still have a few questions:
(a) from 2019 through 2023 you were her on F-1 or what?
(b)What was your visa status for the year 2024 -- F-1 on OPT/CPT with EAD or what ?
(c) Was you visa cancelled/ adjusted at the end of 2023 or what ?
(d) The eligibility for standard deduction is resident for the whole calendar year and not whether one had income on the first day of the year. Why did you leave US on Jan 15th -- was that end of visa or just home leave/vacation ?
(e) Are you still in the USA or back in Deutschland ?
I will circle back once I hear from you
