U.S. treaty partners require the IRS to certify that the company or person claiming treaty benefits is a resident of the United States for the federal tax purposes. The IRS provides this residency certification on Form 6166.  This letter is typically referred to U.S. Residency Certification.

Form 6166 is a letter printed on U.S. Department of Treasury stationary certifying that the company or person is a resident of the United States for purposes of income tax laws of the United States. You may use this form to claim income tax treaty benefits and certain other tax benefits in foreign countries.
