The Biden administration created a “humanitarian parole” program that allows Cubans, Haitians, Nicaraguans, and Venezuelans to stay in the U.S. for two years, but participants — who have legal permission to be here — must apply online with a financial sponsor, and they must be screened, vetted, and authorized for travel. Biden exercised this “parole” authority, which, under a 1952 law, allows him to admit people “only on a case-by-case basis for urgent humanitarian reasons or significant public benefit.”
