On his first day in office, President Trump shut down the CBP One mobile application that facilitated the legal entry of migrants into the U.S. at certain ports of entry. Why it matters: Thousands of people are left stranded in Mexico,

The CBP One app has been highly popular, functioning as an online lottery system that grants appointments to 1,450 people daily at eight border crossings. These individuals enter the U.S. under immigration "parole," a presidential authority that Joe Biden has exercised more frequently than any other president since its creation in 1952.

Since CBP One app was fully rolled out in January 2023, more than half a million immigrants have been admitted into the United States.

About 200 migrants who had their CBP One immigration appointments canceled when President Trump was sworn into office are refusing to leave the San Ysidro border checkpoint until they are seen.

The CBP One App, used by migrants to notify the U.S. government of their intention to arrive at a port of entry and provided resources, has been shut down by the Trump Administration.

Migrants who waited months to cross the U.S. border with Mexico learned their CBP One appointments had been canceled moments after Donald Trump was sworn in as president.

The Trump administration Monday ended use of a border app called CBP One that has allowed nearly 1 million people to legally enter the United States with eligibility to work.

Just hours after the inauguration, migrants with CBP One appointments along the U.S.-Mexico border learned that all CBP One appointments were canceled.
