Many migrants crossed the Rio Bravo River to return to Mexico from the United States after the US Texas National Guard members extended razor wire to deter migrant crossing. Most migrants crossing the border at Ciudad Juarez in Mexico were from Venezuela.

Asylum seekers heading to the United States travelled aboard a train after thousands of migrants already crossed the borders in the last few days. According to experts, the United States cannot detain and process migrants at the crossing. Thus, the administration cannot carry out the harsh penalties announced by the US government in May.

US Customs and Border Protection (CBP) told Reuters they were "safely and efficiently" processing migrants. They would impose consequences, including deportation for migrants staying without a legal basis in the United States. However, the authorities released some asylum seekers into the US with a future court date rather than being deported.

On Thursday, Mexican President Manuel Lopez Obrador criticised the lack of an international plan to help countries lift their citizens out of poverty and avoid a migration drive. He lauded President Biden for creating legal pathways for migrants. However, he said they need expansion.

On Wednesday evening, several dozen people prepared to spend the night sleeping on the ground at a border entry point in Tijuana on the other side of the border from San Diego. They had early appointments the next day, secured through a mobile app called CBP One, to enter the United States and request asylum.
