Federal immigration authorities reportedly are using domestic air travel information to locate and arrest noncitizens suspected of overstaying their authorized periods of admission.

Authorities have made at least 27 arrests of noncitizens suspected of overstay at airports in at least nine states across the country, from California to Virginia, according to an ABC News report.

The Transportation Security Administration (TSA) has proposed delaying enforcement of the REAL ID requirement for passengers of domestic airlines to give travelers two more years to update to REAL ID-compliant identifications. The proposal is open for comments until Oct. 15, 2024.

The REAL ID Act was passed by Congress based on the 9/11 Commission’s recommendations.
