President Trump has repeatedly called for Congress to end America's family reunification immigration program, what he calls "chain migration," but it turns out that his in-laws probably benefited from the program. Melania Trump's parents, Viktor and Amalija Knavs, have green cards, or legal permanent residence, and while neither the Knavs family nor the White House will say how they obtained residency, immigration lawyers say their daughter's sponsorship is probably the only possibility. Melania Trump became a U.S. citizen in 2006, and under current U.S. immigration law, U.S. citizens can sponsor close relatives like their parents or siblings for green cards. President Trump wants to restrict green card sponsorship to only the spouses and non-adult children of U.S. citizens.
