Multiple Nigerian outlets report that the Trump administration has expanded US immigration enforcement at airports by arresting foreign nationals whose visas have expired while they are traveling. The reports, citing coverage from The New York Times, say the arrests are taking place at major airports across the United States and are being carried out as part of broader efforts to identify and detain people who are not in compliance with visa requirements. One outlet specifically notes concerns involving Nigerians and other foreign nationals, and another describes the action as beginning at airports nationwide. The reporting indicates that the measures target travelers arriving or transiting through airports with expired US visas, leading to arrests during routine travel processing. The sources do not provide detailed figures, legal filings, or the precise policy guidance underpinning the arrests, but they consistently characterize the development as a widening of airport-level enforcement against visa overstays and similar immigration status violations. The accounts also do not outline whether individuals are immediately deported or released pending further proceedings.
