Citizens of Mexico must apply for a TN visa stamp at a U.S. Embassy or Consulate overseas with similar supporting documents as for Canadians as listed above. See the Mexico section on the NAFTA website. For updated information regarding procedures and visa application fees, visit the specific Consulate’s website. Visas are issued only by United States consulates and embassies outside the U.S.
The U.S. Department of State provides general information on visa wait times. Though you should always contact the U.S. consulate or embassy for information on processing times, you may use the U.S. Department of State's Visa Wait Times as a guide.
