Visto profissional USMCA-TN (cidadãos mexicanos) — subcidadania do lado dos EUA

MX-BIL-USMCA-02-TN documents the US-side implementation of the USMCA-TN professional visa category for Mexican citizens specifically. This is a sub-set of the broader USMCA Chapter 16 framework documented in MX-BIL-USMCA-01, focusing on the procedural mechanics as they apply to Mexican nationals presenting at US ports of entry or applying through the US Embassy in Mexico City.

TN (Trade NAFTA/USMCA) status allows citizens of Mexico and Canada to enter the United States temporarily to work in approximately 60 professional occupations listed in USMCA Appendix 2. For Mexican nationals (unlike Canadian nationals), a valid TN visa must be obtained from the US Embassy or Consulate in Mexico before entry — or the TN status may be granted at a US port of entry with advance preparation. This procedural difference reflects US-Mexico border management practices distinct from the US-Canada border (where Canadian nationals may apply for TN at POE without a prior visa).

The "sub-citizenship US-side" characterization in the route name reflects that TN status creates a US-law status (nonimmigrant visa/admission) for Mexican citizens that confers specific rights and privileges within US territory — professional employment authorization, multiple-entry admission for the duration of status, and eligibility for dependent TD status for accompanying family members — without creating any pathway toward US permanent residency or naturalization.

• Citizenship requirement: Mexican CITIZEN only — US Lawful Permanent Residents who are Mexican nationals do NOT qualify for TN; must present Mexican passport
• Professional occupation: Must be listed in USMCA Appendix 2 (approximately 60 professions); examples: accountants (CPA or Mexican equivalent), computer systems analysts, engineers (all disciplines), lawyers (LLB/JD), management consultants (baccalaureate + 5y experience), medical/allied health professionals, scientists, teachers/professors
• Qualifying credentials: Specific to each profession — degree requirements, licenses, professional certifications as specified in Appendix 2 notes
• US employer requirement: Must have a US employer offering a specific professional position; self-employment NOT permitted
• Temporary intent: TN is a strict nonimmigrant status — dual intent (simultaneous pursuit of green card) is generally not permitted in standard TN admission (unlike H-1B which permits dual intent)

Common TN professions for Mexican nationals: Computer systems analyst (baccalaureate), accountant (baccalaureate), engineer (baccalaureate), management consultant (baccalaureate + 5 years of experience OR postgraduate degree in management specialty), scientific technician/technologist, hotel manager, physical therapist

Option A — US Embassy Mexico (visa + POE):

1. Mexican citizen obtains letter from US employer confirming: position, credentials required, salary, and TN-basis compliance
2. Schedule and attend DS-160 nonimmigrant visa interview at US Embassy Mexico City or US Consulate (multiple locations in Mexico)
3. Pay visa fee (currently $185 MXN-equivalent); biometric enrollment
4. Consular officer adjudicates TN visa on Mexican passport (notation: "TN-MX" or equivalent)
5. Mexican citizen presents at US POE: TN visa stamp + passport + employer letter + credentials
6. CBP officer admits for up to 3 years; I-94 issued with TN status and end date

Option B — POE application without prior TN visa:

1. Mexican citizen prepares comprehensive documentation package: employer letter, credentials, credentials translations if needed
2. Presents at US land border POE or international airport in primary inspection
3. CBP officer evaluates TN eligibility at POE; if approved, grants TN admission and issues I-94 for up to 3 years
4. This option carries higher risk of delays; Option A (embassy visa) provides pre-screening

Extensions and renewals:

• TN status may be extended in 3-year increments; no cap on number of renewals
• USCIS Form I-129 petition or CBP POE re-admission may be used for extensions
• Each renewal requires current employer letter and credential documentation

• US implementation: INA §214(e) (nonimmigrant TN status) + 8 CFR §214.6 (TN regulations) + USCIS Policy Manual Volume 2 Part I
• Visa issuance: 22 CFR §41.12 (TN visa classification); US Embassy Mexico + 53 US consulates in Mexico process TN applications
• Operative period: 2020-07-01 → present (USMCA successor to NAFTA TN since 1994-01-01)
