Thousands of migrants have been making their way to the US border as the Title 42 immigration law changes.
The rule, which had enabled the swift expulsion of migrants, has now expired.
Amid uncertainty and misinformation surrounding how entry restrictions will change, many fear that it will make access to the US more difficult.
Migrants won’t be allowed in if they arrive at the border without first applying online, or seeking asylum in a country they passed through to reach the United States.
Anyone caught crossing the border illegally won’t be allowed to return to the US for five years and, if they do, they face criminal prosecution.
Record numbers had made their way to the US southern border in the hope of crossing before the midnight deadline.
