Former expat - W2 and 1042s forms

@oussyluv Due to reviewing my previous answer, I had to make changes after researching this a little further. According to this link from IRS.gov, to file a non-resident US return, you must file a return if:

1. A nonresident alien individual engaged or considered to be engaged in a trade or business in the United States during the year.
2. A nonresident alien individual who is not engaged in a trade or business in the United States and has U.S. income on which the tax liability was not satisfied by the withholding of tax at the source.
3. A representative or agent responsible for filing the return of an individual described in (1) or (2),
4. A fiduciary for a nonresident alien estate or trust, or
5. A resident or domestic fiduciary, or other person, charged with the care of the person or property of a nonresident individual may be required to file an income tax return for that individual and pay the tax (Refer to Treas. Reg. 1.6012-3(b)).

You may need to file a non-resident return if your W2 does not have tax withheld from your W2 in accordance with the second point listed above. Also the 401k withdrawal information reported on the 1042S should be reported.  Please view this IRS link regarding reporting requirements for US income.
