Registration with the U.S. Embassy or Consulate makes your presence and whereabouts known, in case it is necessary for a consular officer to contact you in an emergency. During a disaster overseas, American consular officers can assist in evacuation were that to become necessary, but they cannot assist you if they do not know where you are. You can register with the nearest U.S. Embassy or Consulate through the State Department’s travel registration web site.
Additional Information: Travelers going to Mexico over Spring Break should refer to the Department of State’s Country Specific Information for Mexico, the publication Tips for Student Travelers, and the publication Help for American Victims of Crime Overseas.
