Происхождение нескольких поколений (реформа после 2021 года — диаспора неограниченного числа поколений)

This route captures the specific multi-generational dimension of the 2021 Art 30 A II reform — the ability of third-generation, fourth-generation, and beyond Mexican descendants born outside Mexico to claim Mexican nationality by birth. While MX-DSC-01 documents the general jus sanguinis framework, this route focuses on the cascade-: that the reform enables unlimited generational transmission without any generation cap.

Prior to DOF 2021-05-17, SCJN Segunda Sala Contradicción de Tesis 212/2019 (tesis 2a./J. 167/2019) applied strict construction to multi-generational facts. Specifically, the pre-2021 text required that a child born abroad have a parent who was themselves "mexicano por nacimiento" — but what if that parent was also born abroad? The SCJN tesis maintained strict evidentiary requirements and in practice created uncertainty about whether grandchildren of Mexicans (whose Mexican parent was born abroad) could claim Art 30 A II.

The DOF 2021-05-17 amendment resolved this decisively by eliminating the implicit territorial-birth requirement. Under the post-2021 text, any person born abroad with any Mexican ancestor in the direct line — grandfather, great-grandfather, however many generations — can claim Mexican nationality by birth provided they can document the chain. The SCJN tesis on strict construction of specific supuestos survived but is displaced on the key multi-generational fact.

The DOF junio 2024 reform to CNDOC Arts 314 + 1144 eliminated the apostilla requirement for nationality-acreditando documents, which is operationally critical for diaspora documentation chains involving foreign birth certificates and foreign acts of registration across multiple generations.

• Born outside Mexico in any generation
• Documentary chain proving Mexican ancestor in direct line (parents, grandparents, great-grandparents, etc.)
• Each link in the chain must be documented (birth certificates, DNN-1 certificates, Cartas de Naturalización where applicable)
• Apostilla no longer required for foreign documents per DOF junio 2024 reform
• No age limit — lifetime availability

MX eligibility framework (DSC): bucket-specific anchored in CPEUM Art 30 (Apartado A jus soli + Apartado B jus sanguinis) + Ley de Nacionalidad 1998 (DOF 1998-01-23, última reforma DOF 2012-04-23) + Reglamento DOF 2009-06-17 (Calderón). Constitutional ceiling CPEUM Art 30/32/37. DSC eligibility: CPEUM Art 30 Apartado A fracción II (Mexican parent born in Mexico) + fracción III (Mexican parent born outside Mexico — multi-generational Art 30 reform DOF 2021-05-17 Sheinbaum-era). Operative since 1934-01-18 reform (Apartado A current architecture); 1969/1974/1997 reforms progressively eliminated gender asymmetries.

1. Compile documentary chain: each generation's birth certificate tracing back to a confirmed mexicano por nacimiento ancestor
2. Since DOF junio 2024, foreign documents used in the chain do not require apostilla — legalización or consulado certification may suffice per Reglamento Art 16
3. Apply via SINNA portal or SRE-DGAJ / consulate
4. SRE-DGAJ reviews the chain; issues DNN-1 subcategory B upon approval
5. Complex multi-generational chains may require an in-person appointment at SRE-DGAJ CDMX rather than consulate-level processing
