In total, 23 states don’t meet the federal requirements and have either received an extension or have requested an extension beyond the January 22, 2018 cut-off date. At this point, it’s safe to assume that every state will receive an extension through October 10, 2018, and potentially additional extensions that will allow travelers to continue using their IDs at airport security with no problems. Hopefully, every state will make ID cards that meet the law’s requirements by October 1, 2020, because that’s when the TSA will no longer accept anything other than a REAL ID-compliant ID or driver’s license.
It's worth noting that five states -- Michigan, Minnesota, New York, Vermont, and Washington -- currently offer Enhanced Driver's Licenses, which the TSA will accept at airport security checkpoints, according to DHS. Getting an EDL can sometimes cost more than a regular driver's license, though. But at least it's better than having to whip our your passport at airport security every time you fly.
