Gonzales v. Thomas: Courts Must Let the BIA Decide a Proposed Social Group in the First Instance

By Aneeta Mishra and Timothy Chan

Published August 26, 2026

Gonzales v. Thomas applied the ordinary remand rule after the Board had rejected asylum on another ground without deciding the proposed family-based social group.

The agency had not resolved the dispositive issue

The Board’s decision did not determine whether the family relationship satisfied the statutory particular-social-group category.

The court of appeals could not supply the agency’s answer

Questions committed initially to the agency require its expertise, policy judgment, and fact-sensitive application before judicial review.

Remand preserves the proper allocation of authority

A reviewing court evaluates the reasons the agency actually gave; it does not make an unaddressed immigration determination itself.

Remand did not guarantee asylum

The Board still had to address group cognizability, nexus, other eligibility elements, bars, and discretionary relief on the record.

Key takeaways

• Identify which elements the immigration judge and Board actually decided.
• Ask the Board to address preserved alternative grounds.
• Frame the proposed group with record evidence.
• Seek remand rather than an appellate factual or policy determination in the first instance.
