Introduction
A federal case out of San Antonio, Texas has concluded with two defendants sentenced to a combined 32 years in federal prison for the sex trafficking of a 16-year-old orphan. USCIS played a direct role in making that outcome possible. The U.S. Attorney’s Office announced that U.S. Citizenship and Immigration Services contributed meaningfully to the investigation through immigration records analysis, jail call review, and expert guidance provided to law enforcement partners throughout the case. As a result, the outcome illustrates how USCIS immigration enforcement cooperation functions in practice. It extends the agency’s reach well beyond its more commonly known role in adjudicating petitions and applications.
Background
USCIS is best known to the public as the agency that processes visa petitions, green card applications, naturalization requests, and related immigration benefits. Less visible is the agency’s law enforcement support function. Through this function, it assists federal and local investigators by providing immigration records, status verification, and subject-matter expertise in active criminal cases. While this support capacity has existed for years, specific cases that publicly document it are relatively rare. However, when they do surface, they offer a clearer picture of how immigration agencies interact with broader federal and local law enforcement networks. This is particularly relevant in cases involving individuals who may lack legal immigration status and whose immigration histories are relevant to a criminal investigation.
What Occurred in This Case
Giannys Alexandra Ramirez-Fernandez, 21, and Nelson Adrian Perez-Martinez, 23, both Venezuelan nationals, were arrested in San Antonio on July 30, 2024, in connection with an ongoing domestic sex trafficking investigation. Notably, court records document that in July 2024, the two traveled with a 16-year-old orphan from Colombia through Kentucky and into San Antonio. There, they facilitated the child’s exploitation for commercial sex acts at approximately six motels. The rooms were paid for in cash sourced from the proceeds of those acts.
Ramirez-Fernandez pleaded guilty on September 17, 2025, to charges including conspiracy to traffic children, aiding in child sex trafficking, and transporting a minor for illegal sexual activity. By contrast, Perez-Martinez faced a jury trial after federal prosecutors brought additional charges against him in October 2025. On February 23, 2026, a jury found him guilty on all counts. U.S. District Judge Fred Biery sentenced Perez-Martinez to 240 months — 20 years — in federal prison with lifetime supervised release. He sentenced Ramirez-Fernandez to 150 months, or 12 and a half years.
USCIS contributed to the investigation by conducting immigration record checks on individuals connected to the case, reviewing jail calls for information relevant to the prosecution, and providing immigration guidance and expertise to the investigative team. Moreover, the broader case was a multi-agency effort involving ICE Homeland Security Investigations, the FBI, and the San Antonio Police Department. The prosecution was handled by the U.S. Attorney’s Office for the Western District of Texas.
Who Is Affected
This announcement does not affect pending immigration applications, visa categories, or benefit eligibility for any class of applicants. It is not a policy change, a regulatory update, or a new procedural requirement. The direct parties — the two defendants — have been sentenced and their cases resolved through the federal criminal justice system.
The broader significance for the immigration community involves awareness. Individuals, employers, attorneys, and advocates who work with vulnerable populations — particularly unaccompanied minors, trafficking survivors, or individuals in irregular immigration status — should understand that USCIS actively participates in criminal investigations where immigration records and status are material to the case. Although this is not a new development, cases like this one confirm that the agency’s law enforcement cooperation function operates in real and consequential ways.
Practical Implications
For immigration practitioners and the communities they serve, this case reinforces several points worth understanding. First, immigration records held by USCIS — including records of applications, status histories, and associated information — can be accessed and used in the context of federal criminal investigations. This is consistent with longstanding inter-agency data-sharing frameworks. Importantly, it is not unique to this administration or this case.
Second, the case highlights the T visa and related humanitarian protections that exist specifically for trafficking survivors. Individuals who are victims of severe forms of trafficking — including minors who have been commercially exploited — may be eligible for immigration relief and support services through established federal programs. Therefore, understanding these pathways matters for anyone working in social services, law enforcement support, or immigration advocacy.
Third, the involvement of USCIS in a criminal prosecution underscores that the agency’s role in any given case is not always confined to benefits processing. In fact, for practitioners advising clients with complex backgrounds or open investigations, this intersection of immigration records and criminal proceedings is an area requiring careful attention.
What to Watch For Next
This announcement does not signal a formal policy change at USCIS, and no regulatory action, comment period, or guidance update is associated with it. As a result, stakeholders interested in USCIS’s law enforcement cooperation activities should monitor the agency’s newsroom for future announcements. Those seeking to report suspected immigration benefit fraud or abuse can do so through the USCIS Tip Form referenced in the agency’s official release. Furthermore, no further developments in this specific case are anticipated, as sentencing has been completed.
