Canadian Snowbird Visa Act This bill amends the Immigration and Nationality Act to authorize the Department of Homeland Security to admit into the United States as a nonimmigrant visitor for a period not to exceed 240 days during any single 365-day period a Canadian citizen who: (1) is at least 50 years old, (2) maintains a Canadian residence and owns a U.S. residence or has rented a U.S. accommodation for the duration of such stay, (3) is not inadmissible or deportable, (4) will not engage in employment or labor for hire in the United States other than for a non U.S.-based person or entity by whom the Canadian citizen was employed in Canada or for whom the Canadian citizen performed services in Canada, and (5) will not seek any form of assistance or benefit under the Personal Responsibility and Work Opportunity Reconciliation Act of 1996. The spouse of such person may be admitted under the same terms except that he or she is not required to separately satisfy the residence/housing requirements. The bill grants a person so admitted nonresident alien tax status.
