The Trump administration is quietly revoking the temporary legal status of people who entered the country via an online appointment app at U.S. border crossings with Mexico. The cancellation of CBP One lacks the fanfare and formality of announcements to end other Biden-era polices for temporary protection. More than 900,000 people came to the U.S. on CBP One. Cancellation notices began landing in inboxes in late March without warning, some telling recipients to leave immediately and others giving them seven days. Targets included U.S. citizens who, according to authorities, were unintended recipients.
