Восстановление мексиканского гражданства (статьи 16–19 Ley Nacionalidad)

Mexican nationals por nacimiento who lost their nationality under the pre-1998 single-nationality regime — by acquiring a foreign nationality — may recover (recuperar) their Mexican nationality through Arts 16-19 of the Ley de Nacionalidad 1998. This Recuperación procedure is a formal legal restoration mechanism that requires positive action by the former national: it is not automatic. The constitutional basis is CPEUM Art 37 Apartado A, which provides absolute non-deprivation of Mexican nationality for persons mexicanos por nacimiento under the post-1997 framework, but that shield is prospective — it applies from 1998-03-20 forward. For persons who lost nationality under the old regime before that date, Recuperación provides the formal legal pathway back.

The Recuperación route is distinct from MX-DSC-05 (Declaratoria de Nacionalidad Mexicana por Nacimiento), which is the simpler documentary declaration available to persons who used or obtained another nationality but never formally renounced Mexican nationality under the old statutory framework. Recuperación applies to persons who definitively lost Mexican nationality under the pre-1998 rule (automatic loss upon voluntary foreign-nationality acquisition under Ley 1934/1993).

Art Cuarto Transitorio of the Ley de Nacionalidad originally created a 5-year window (1998-2003) for Recuperación applications. The DOF 2004-12-02 reform extended this window indefinitely — "en cualquier tiempo." This means Recuperación remains available as of 2026-05-17, with no closing deadline.

• Applicant is a person who was mexicano por nacimiento and definitively lost Mexican nationality under the pre-1998 single-nationality statutory framework (Ley 1934 or Ley 1993) by voluntarily acquiring or using a foreign nationality
• Former Mexican nationality must be documentable (prior acta de nacimiento, Registro Civil records, prior passport, etc.)
• Procedure requires:
• Renuncia oath to the foreign nationality (or relevant foreign state affiliation) — Art 17 applies in adapted form
• Acreditación of prior Mexican nationality (birth certificate, descent documentation)
• Application at SRE-DGAJ with complete documentary package
• Distinguished from MX-DSC-05: Recuperación is for persons who definitively lost nationality (formal cessation under old law); Declaratoria is for persons who used/obtained a foreign nationality but retain a claim to never having formally lost Mexican nationality
• No minimum age requirement
• No residency requirement — recovery is procedural, not predicated on current Mexico residence

3. Submit Recuperación application at SRE-DGAJ; tarifa MXN 1,590
