Argentina

The country's own registry

• Law Ley 26.879 created a national register of DNA profiles for criminal investigations. It was first limited to offences against sexual integrity and was widened by Ley 27.759 (2024). It holds the profiles of adults who have been charged, committed for trial or convicted, and since 2025 it sits within the Ministerio de Seguridad Nacional (arts. 1, 2, 4(e)).

• Law The register is confidential. Its contents are sensitive data, given only to judges or prosecutors for a specific case, and may not be consulted for any other purpose (art. 8).

• Finding No published rule found as of October 27, 2026. No public national sex offender registry was found.

Entry and admissibility

• Law A conviction or a pending case ("antecedentes") in Argentina or abroad, for an offence punishable under Argentine law by 3 years' imprisonment or more, is an impediment to entry and stay. A conviction for an offence punishable by less than 3 years is also an impediment (Ley 25.871 art. 29(c), (d)).

• Law For art. 29, a conviction means any guilty verdict, final or not. "Antecedente" means a formal committal or equivalent step toward trial. Failing to disclose a criminal record or conviction is itself an impediment (art. 29(a)).

• Law The Dirección Nacional de Migraciones may admit someone covered by an impediment for humanitarian or family-reunification reasons, or where the rights of minors are seriously affected. It may never admit a foreigner convicted of, or with antecedentes for, an intentional offence against life, sexual integrity, or the public powers and constitutional order (art. 29).

• Law Anyone covered by an art. 29 impediment must be refused at the border immediately (art. 35(e)).

• Law The current wording of arts. 29, 35, 62 and 63 comes from Decreto de Necesidad y Urgencia 366/2025. Courts have struck down the decree's citizenship articles, and press reports in October 2026 said a challenge was before the Supreme Court. Those reports did not say the immigration articles had been suspended.

  Recheck: Whether the declaration asks about criminal history was not confirmed. Under art. 29(a), failing to disclose a record is itself an impediment.

Residency, employment and housing

• Law An applicant for permanent residence must show they have no criminal record that could justify refusal (Ley 25.871 art. 22). The art. 29 impediments apply to stay as well as entry.

Removal, rehabilitation or waivers

• Law Cancellation and expulsion may be waived for humanitarian or family reasons, but never for someone convicted of an intentional offence against life, sexual integrity, or the public powers and constitutional order (art. 62).

• Law An expulsion based on an intentional crime carries a permanent re-entry ban. The ban can be waived, but not for an intentional offence against sexual integrity (art. 63(d)).

• Law A refusal at the border based on art. 29 carries a re-entry ban of at least 5 years. The refusal can be appealed only from abroad, through an Argentine diplomatic mission (art. 35).

What U.S. rules still apply

• Law U.S. law still applies to the trip itself: registrants must report international travel at least 21 days in advance, and the U.S. may notify the destination country before arrival. See the U.S. travel guide for the notice rule, the passport identifier and how notifications work.
