This proposed rule would ensure that Federal agencies have appropriate flexibility to implement the card-based enforcement provisions of the REAL ID regulations after the May 7 2025 enforcement deadline by explicitly permitting agencies to implement card-based enforcement in phases. This rulemaking proposes that agencies may implement the card-based enforcement provisions through a phased enforcement plan if they determine it is appropriate upon consideration of relevant factors including security operational feasibility and public impact. The proposed rule would also require agencies to coordinate their plans with DHS make the plans publicly available and achieve full enforcement by May 5 2027.
