A constitutional doctrine under which Congress possesses broad authority to regulate the admission, exclusion, and treatment of noncitizens. Federal alienage classifications therefore receive rational-basis review and are upheld if not arbitrary or unreasonable.
Philip Powell, a lawful permanent resident for four years, applied for federal Medicare benefits. The agency denied coverage because he had not yet met the five-year residency threshold. Powell sued, claiming the rule violated equal protection. The court upheld the denial because the federal classification based on alienage satisfied rational-basis review.
Patrick Phan, a lawful permanent resident for six years, sought an affordable-housing tax credit for his landlord. The federal program required eight years of residence for noncitizens. The landlord received no credit, and Phan sued the housing agency. The court rejected the challenge because the federal alienage line was not arbitrary or unreasonable.

Congress holds plenary power over immigration and naturalization. That authority means federal lines based on alienage are reviewed under a deferential standard and upheld if not arbitrary or unreasonable.
Supporting sources
No. The requirement is constitutional because it is rationally related to legitimate goals such as controlling costs and encouraging integration. Federal alienage classifications survive review when they are not arbitrary or unreasonable.
Supporting sources
States lack plenary authority over immigration, so their alienage classifications usually trigger strict scrutiny. Federal classifications receive only rational-basis review because Congress exercises broad national power in this area.
Supporting sources
Yes. The five-year rule advances fiscal and administrative objectives by limiting benefits to those with substantial ties to the United States. The classification is neither arbitrary nor unreasonable under the applicable standard.
