@ducomulder , generally FBAR ( form 114 at FinCena.gov ) and FATCA ( form 8938 ) regs. only apply to US persons ( citizen/GreenCard/ Resident for Tax Purposes ).
Also generally depending on the type of J-1 visa and how long you have been in the USA, you may or may not be a Resident for Tax Purposes.
Are you student/Trainee on J-1 or a Teacher/Researcher ? When did you enter the USA ? Which country are from ?
Thank you, in my case, I was a student doing an internship that lasted 12 months. I entered the beginning of 2022 and left the US in May 2023, back to the Netherlands.
@ducomulder based on the information you have provided so far, I think you were a Resident for Tax purposes during 2022 and a dual-status for 2023. Thus while it may not be mandatory for you to file FBAR ( depending on the exact facts and circumstances ), I see no harm in filing one . I say this because it is not a tax event but it does not harm in filing this . To do this you will have to go to FinCen.gov and search for form 114 -- it is only done on-line and ideally should be done by April 15th . Just in case you come back to USA for training / studies or whatever -- just keeping everything unassailable. On the other-hand if you choose not to file, there is probably no harm.
Is there more I can do for you ?
