@MJ Sally , hope you mean form 8938 -- Specified Foreign Assets Reporting.
(a) The FBAR and FATCA regs apply only to a US person ( citizen/GreenCard /Resident for Tax purposes ).
(b) Note that the trigger values are generally based on the last day of the year ( and yes there is also a "but" in it ).
(c) Your wife's residency ( US personhood) starts from the day she was admitted with the GreenCard or the first day here legally whichever is first ( under GreenCard test ). So it is essentially for the whole of 2024.. Thus , and absent any other or treaty considerations , she was not subject to FBAR/FATCA till then.
However, note that there is no tax consequences of reporting FBAR/ FATCA but willful disregard of the law is heavy penalized.
Is there more I can do for you ?
