When employees travel abroad, flight information is automatically recorded in the Advance Passenger Information System (APIS) database maintained by the Customs and Border Patrol agency. If a scheduled flight is cancelled or rescheduled, the database does not necessarily reflect the updated information. This could affect a petition to renew valid nonimmigrant status, for example, because the beneficiary is required to be in the United States at the time of filing. A Request for Evidence could be issued based on the APIS database indicating the beneficiary was not physically present at the time of filing. A travel tip: Direct your employees to keep documentation to establish their physical presence in the United States if they do not take a scheduled flight.
