From NARSOL: the U.S. State Department has begun canceling valid passports pursuant to authority granted by Congress in 2016 when it passed International Megan’s Law (IML). This has resulted in American citizens being turned back at several foreign destinations recently. Paul Rigney from Registered Citizen Travel Action Group (RTAG) will share his organization’s knowledge regarding IML issues, which we hope will assist those planning to travel outside the United States. In addition, attorney Paul Dubbeling will answer questions regarding potential litigation challenging IML.
