Generally, for U.S. tax purpose, a nonimmigrant or immigrant visa status under U.S. immigration law is different from U.S. tax residency status under U.S. tax law (nonresident alien, resident alien, or dual-status alien). Visa status under immigration law may be relevant to U.S. taxation in limited situations, such as: Whether to count the days of presence in the United States for purposes of the Substantial Presence Test in order to determine U.S. tax residency in a tax year. Internal Revenue Code (IRC) exceptions based on visa status. Application of U.S. income tax treaty benefits.
