ISSUE: I have an odd problem with my baka American buddy who started in Japan 15 years ago, has lived in China for the past 13 years, and never filed any US income taxes for the "Foreign Earned Income Exclusion."
QUESTION: My baka buddy "claims" he went to the district IRS office in Iowa (his tax home) and they supposedly/bizarrely told him he had, "no tax liability" and didn't ask him to file late returns or anything on his past 15 years of crappy, under 3~4 mil yen/year income.
Is there a special China loophole, that Japan-based Americans do not get?

ALSO: He has a new Chinese wife that he's trying to take back to the States. Will his 15-year, non-filing, tax status with the IRS effect her getting a spouse visa?
