Requires most nonimmigrant visitors to provide a cash payment or bond of $5,000–$50,000 when seeking entry to the United States. If they overstay, the bond is automatically forfeited without appeal, they must be removed, and they face a multi‑year bar (4–12 years) on most lawful immigration status. Forfeited funds are used to pay for detention and transportation costs.

It also narrows when people can apply for asylum or withholding of removal and limits the Department of Homeland Security’s ability to alter these rules by regulation. The aim is to deter overstays and tighten immigration enforcement, while shifting certain enforcement costs to violators.
