As of February 22, 2010, the Department of State eliminated all nonimmigrant visa reciprocity fees for Mexican citizens and updated the reciprocity schedule. Under the previous schedule, a provision for Mexican TN and TD visa holders allowed them to pay for up to three years of visa validity at the time of the first issuance. The new schedule no longer includes that provision, and TN and TD visa validity is now limited to 12 months, the same period of time permitted U.S. citizens working in Mexico before they must renew their FM3 work permits. There is no fee for the TN and TD visas. All applicants must still pay the application fee, however. The visa reciprocity table is available here.
