U.S. and Polish Citizen: Which Passport Do You Use?
The U.S.-law side of dual U.S.-Polish nationality, including the U.S. passport rule, ESTA, and why Polish-side entry rules must be checked separately.
Direct answer
Short answer
The U.S. Department of State states that U.S. citizens, including dual nationals, must enter and depart the United States using a U.S. passport. A U.S. citizen is not eligible for a U.S. visa and should not use the Polish passport to obtain ESTA for travel to the United States.

For the United States, use the U.S. passport
The rule applies to dual nationals too. The foreign passport is not a substitute for U.S.-citizen travel to or from the United States.
A U.S. citizen should not use ESTA as a workaround
The Department of State says dual U.S. citizens are not eligible for a U.S. visa and may not use the foreign passport to seek ESTA for U.S. travel.
Poland may have its own passport rules
Polish entry, exit, identity, military, tax, or nationality consequences are questions of Polish law and should be checked with current Polish authorities or Polish counsel.
Keep citizenship evidence clean
A valid U.S. passport, Certificate of Naturalization, Certificate of Citizenship, qualifying birth certificate, or CRBA may serve different proof functions.
Questions people actually ask
Frequently asked questions
Can a dual U.S.-Polish citizen get ESTA on the Polish passport?
The Department of State says U.S. citizens are not eligible for ESTA as foreign visitors to the United States.
Does getting Polish citizenship cancel U.S. citizenship?
U.S. law generally permits dual nationality; loss of U.S. nationality requires the legal standards for relinquishment or renunciation, not merely acquiring another nationality.
Which passport should I show in Poland?
That is a Polish entry/exit-law question. Check current Polish government requirements.

Put the actual record on the table
Dates, entries, exits, petitions, notices, court records, business records, credentials, and the next deadline usually matter more than the label someone gave the problem.
