@chrisgh now you got me --- I know of no requirement of 330 days for FATCA ( form 8938 ). Here is a comparison of FBAR and FATCA -- it just says " living outside the US" -- I am interpreting this to mean a tax home ( for surely the higher threshold will not apply if someone is vising his grandparents over the Christmas/ New Years holidays -- that would not be logical )
Comparison of Form 8938 and FBAR requirements | Internal Revenue Service.
Does this make sense ?
