There have been few reports of stranded travelers following implementation of a new rule requiring U.S. airline passengers to show a passport upon their return from Mexico, Canada or the Caribbean.
Most travelers who forgot about the new requirement were allowed to enter after receiving a warning and a passport application. But their names were entered into the agency’s computer system, and they will be scrutinized if it happens again.
“Nobody’s being turned away,” said Roxanne Hercules, an agency spokesman in Northern California. “These are mostly U.S. citizens coming home from traveling. We just are trying to inform them of the new rules.“
