The Temporary Family Visitation Act creates a new temporary visa category allowing foreign relatives of U.S. citizens and lawful permanent residents to visit the United States for family purposes. This visa would be limited to 90 days per calendar year and would apply to spouses, children, parents, grandparents, siblings, aunts, uncles, nieces, nephews, and other extended family members. To obtain this visa, the sponsoring U.S. citizen or permanent resident must submit a declaration of support, the visiting relative must obtain short-term travel medical insurance, and the visitor must demonstrate intent to return home after their stay. The bill also prevents sponsors from petitioning for future family visits if a previously sponsored relative overstayed their authorized admission period, though the Department of Homeland Security can waive this restriction in cases of extraordinary circumstances. No specific funding or implementation timeline is outlined in the legislation.
