@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 ?
