U.S. Citizen Stopped in an Immigration Operation: What to Document
A documentation-focused resource for Polish-American U.S. citizens who are questioned or temporarily detained during an immigration operation and need to establish identity and citizenship.
Direct answer
Short answer
A U.S. citizen is not removable as a noncitizen under the immigration laws. If a citizenship or identity dispute occurs during an enforcement encounter, preserve the names of agencies and officers, location, time, witnesses, documents shown, statements made, and any paperwork received, and assemble primary citizenship evidence immediately.

Know the strongest citizenship documents
A valid U.S. passport, qualifying U.S. birth certificate, CRBA, Certificate of Naturalization, or Certificate of Citizenship can serve as primary proof in different settings.
Create the encounter record while details are fresh
Record agency, officers, location, duration, statements, witnesses, property taken, searches, handcuffing or transport, and the exact document that ended or continued the encounter.
A Polish passport does not cancel U.S. citizenship
Dual nationality can create travel and consular complexities, but the U.S. citizenship claim should be established with U.S. citizenship evidence.
A mistaken stop can raise legal issues beyond immigration status
Potential remedies depend on who acted, what happened, how long it lasted, what the officers knew, and what records exist. Preserve evidence before evaluating claims.

A valid full-validity U.S. passport is recognized as primary citizenship evidence in Department of State guidance.
Can a dual U.S.-Polish citizen be treated as only Polish in the United States?
