Portugal is part of the US Visa Waiver Program. Portuguese passport holders enter the United States for up to 90 days without a visa, but must obtain an approved ESTA (Electronic System for Travel Authorization) before boarding. The ESTA costs USD 21, is valid for 2 years or until the passport expires, and covers multiple entries. Apply at the official CBP site (esta.cbp.dhs.gov) at least 72 hours before departure.

The 90-day stay cannot be extended, and you cannot change immigration status while in the US on the Visa Waiver Program.
