What documents do I need to submit for tax filings or US residency certification (IRS Form 8802/Form 6166)?
While Form 6166 is the official TRC used to show residency, the actual application for IRS Form 6166 is Form 8802, the “Application for United States Residency Certification.” This form would be submitted to the IRS to obtain Form 6166.
