New U.S. immigration and travel rules took effect on December 26, 2025, implementing stricter border checks and expanding the use of biometric identification for non-U.S. citizens, including Green Card holders. All travelers will have their photographs taken upon entry and exit, with no age exemptions. Fingerprints and iris scans may also be collected. Green Card holders from 19 specific countries face intensified reviews and questioning. Officials anticipate longer processing times at ports of entry due to these enhanced security measures.
