How the U.S. Patrols Its Borders

·  U.S. Customs and Border Protection, along with a few agencies, regulates trade and travel at U.S. ports of entry and across the country’s borders.

·  While President Biden reversed some Trump-era policies, which tightened security at the U.S.-Mexico border, he kept a troop presence there and restricted asylum access in response to a record number of migrant arrivals.
