Mexico Mexico loosens travel rule for unaccompanied minors By Gay Nagle Myers / January 31, 2013 Share 1 -- Unaccompanied minors traveling to Mexico no longer need a notarized letter from their parent or guardian authorizing the trip. The regulation has been suspended for a year by the Ministry of Tourism and National Institute of Migration. Prior to the temporary suspension, anyone under 18 traveling alone or accompanied by a single parent or legal guardian had to carry a notarized letter signed by both parents or by the one not traveling with the minor granting permission to enter/exit the country. The regulation had proved to be a cumbersome roadblock for student groups entering Mexico or for kids traveling solo or with just one parent. Follow Gay Nagle Myers on Twitter @gnmtravelweekly.
