Pangilinan: Equity Could Not Confer Citizenship Outside Congress’s Terms

By Aneeta Mishra and Timothy Chan

Published August 13, 2026

INS v. Pangilinan involved Filipino nationals who had served honorably with United States forces during World War II and sought citizenship under a special naturalization law decades after its filing deadline.

Congress created a temporary wartime naturalization route

The Nationality Act provisions relaxed ordinary requirements for qualifying service members but required petitions by December 31, 1946. The respondents did not complete applications within that period.

The lower court relied on historical government conduct

The Ninth Circuit concluded that the government’s failure to maintain a naturalization representative in the Philippines during part of the filing window warranted equitable relief and ordered naturalization.

Naturalization must rest on statutory authority

The Supreme Court held that courts have no equitable power to confer citizenship contrary to statutory requirements. Neither estoppel nor a general remedial power could extend an expired congressional deadline.

The judgments granting citizenship were reversed

The result did not minimize the respondents’ military service; it enforced Congress’s exclusive authority over naturalization terms. Current applicants must identify a presently valid statutory path and satisfy every required filing and eligibility condition.

Key takeaways

• Identify the exact citizenship statute and confirm it remains in force.
• Calendar every filing, residence, service, and physical-presence requirement.
• Do not assume hardship or government error lets a court waive statutory limits.
• Develop any alternative current route to status or citizenship separately.
