By law, U.S. citizens, including dual nationals, must use a U.S. passport to enter and exit the United States. U.S. citizens are not eligible for a U.S. visa. U.S./Portugal dual citizens are advised to carry both valid passports (U.S. and Portugal) when traveling to/from the United States. The dual citizen will be required to present their U.S. passport at U.S. immigration and might be requested to present their Portuguese passport when going through Portuguese immigration.
