Background

The petitioner, Cenia P.R., was detained by U.S. Border Patrol on or about November 7, 2025, shortly after entering the country. She is currently held by Immigration and Customs Enforcement (ICE) at the El Valle Detention Center in Willacy County, Texas. On May 26, 2026, an Immigration Judge denied her request for a bond hearing, citing a lack of jurisdiction.

Following the bond denial, the petitioner filed a writ of habeas corpus in federal district court. She presented two main arguments for her release. First, she claimed that her mandatory detention under 8 U.S.C. § 1225(b)(2) was an unlawful application of the Immigration and Nationality Act (INA). Second, she argued that her continued detention without a bond hearing to determine if she is a flight risk or a danger to the community violates her constitutional right to due process.

The Court’s Holding

United States Magistrate Judge Karen Betancourt recommended that the District Court deny the habeas petition. The court addressed both of the petitioner’s claims, finding neither had merit under current precedent. It concluded that the petitioner’s detention was statutorily authorized and constitutionally permissible.

Citing the Fifth Circuit’s decision in Buenrostro-Mendez v. Bondi, the court found that the petitioner was lawfully detainable under 8 U.S.C. § 1225(b)(2). Addressing the due process claim, the court relied on the Supreme Court’s ruling in Demore v. Kim, which established that detention during removal proceedings is generally a permissible part of that process. The court distinguished the petitioner’s situation from cases involving aliens who have established “substantial connections” with the United States. Because the petitioner had just entered the country, the court found she was “entitled only to those due process rights as are provided by… Congress.” As the court found no punitive purpose in her detention, it concluded no extra-statutory due process rights had been violated.

Key Takeaways

  • In the Fifth Circuit, individuals who have recently entered the U.S. can be subject to mandatory detention without a bond hearing under 8 U.S.C. § 1225(b)(2).
  • The constitutional right to due process does not automatically guarantee a bond hearing for non-citizens detained during removal proceedings, especially for recent arrivals.
  • Under the “entry fiction” doctrine, the due process rights of aliens who have not established substantial connections to the U.S. are limited to those granted by statute, not broader constitutional protections.

Why It Matters

This report and recommendation reinforces the significant legal hurdles faced by recently arrived immigrants challenging their mandatory detention in the Fifth Circuit. It affirms the government’s authority to detain individuals during the pendency of their removal proceedings without a bond hearing, based on the statutory framework created by Congress.

For legal practitioners, the decision underscores that constitutional due process challenges to mandatory detention are unlikely to succeed for this class of detainees unless they can demonstrate that the detention is punitive or has become unconstitutionally prolonged. The court’s reasoning highlights a strict interpretation of an arriving alien’s limited rights, drawing a sharp distinction between individuals who have just crossed the border and those who have developed deeper ties to the country.
