Scenario -
American Citizen wife arrives at Airport in Belize with her Legal Resident Alien Green Card Holding Italian husband. He has had his Legal Residency established since 1972.
Upon check in - they realize he left HIS green card on the front hall table prior to departing for their honeymoon.
What is the law that would allow - for example ONLY - United Airlines Ticket Agent/Check In Agent in Belize City to deny the husband boarding the plane?
Per Houston CBP - For Example - Airline was wrong. Their CUSTOMER had Social Security Card, a COPY of his Green Card, US driver's license, proof of employment, library card, marriage license, etc. etc. He should not have been denied passage.
He should have been allowed on the flight, Processed through Deferred Inspections at the Airport - and they would have fined/collected $520 from him and told him not to do it again.
There is a break in the process system. I intend to follow up with the Consulate in Belize and the Airline we flew - but trying to understand why an employee of a service provider felt they had legal authority to act on CBP's behalf?
