The short answer to your question would be no, you do not need
to file an FBAR form (for 2015), if you are a nonresident alien (foreign citizen) who lived in the
United States for just two weeks in the relevant year. A longer answer to your question is more detailed, so
please continue reading.
There are actually (2) separate foreign financial account
disclosure forms that can be applicable to US citizens, resident aliens,
and nonresident aliens (and your self-described circumstances would
seem to place you in the nonresident alien category).
Of these (2) different disclosure forms, each also has different
reporting rules. One is known as IRS Form 8938, which is filed along with a US income tax return. The other is FinCen
Form 114, which can only be filed via a specific government site on the internet. The following
Internal Revenue Service (IRS) webpage describes both of these disclosure documents in some detail, and provides
their US dollar value reporting levels (for 2016):
https://www.irs.gov/businesses/comparison-of-form-8938-and-fbar-requirements
After visiting that link, you can see from reading the IRS
summary there that FBAR (a.k.a. FinCen Form 114) does not apply to
nonresident aliens. In other words, nonresident aliens are exempt from
FBAR.
Form 8938 disclosure requirements can apply to
nonresident aliens, but only those who make an election to be treated as
a resident alien for purposes of filing a joint income tax return,
along with a US citizen or US resident alien; or those nonresident
aliens who are a bona fide resident of either American Samoa or Puerto
Rico.
Unless one of those special situations describes you, then none of these foreign account disclosures are applicable to you. Thus, as a nonresident alien, you do not need to
file either Form 8938 or a FinCen 114 (FBAR) disclosure in most instances. Please keep in mind that the foreign financial account disclosure rules change, however, if or when a nonresident alien becomes a resident alien (for income tax purposes).
Thank you for asking this question.
