United States entry requirements for Portugal passport holders
Portuguese passport holders must obtain an ESTA (Electronic System for Travel Authorization) before flying to the United States for tourism or business stays under 90 days. This requirement is in effect for 2026. The ESTA is an online authorization, not a visa, and must be secured at least 72 hours before departure.
Entry requirements
| Requirement | Details | Status |
|---|---|---|
| ESTA (Electronic System for Travel Authorization)You need this online authorization before you travel; without it you won't be allowed to board. Visa waiver entry permit | Portuguese citizens must obtain an approved ESTA before boarding a flight to the US. Apply online at the official ESTA website (https://esta.cbp.dhs.gov/). The fee is US$40.27 ($4.00 processing + $36.27 authorization). Processing is often instant, but allow up to 72 hours. Each authorization is valid for up to 2 years or until your passport expires, whichever comes first. | Required |
| Passport validityYour passport must not expire soon after your trip; it needs to be valid for half a year beyond your stay. Must be valid for 6 months beyond your stay | Your Portuguese passport must be valid for at least 6 months beyond your intended stay in the US. For a 90-day stay, ensure your passport is valid for at least 6 months after your departure date from the US. | Required |
| Blank passport pagesYou need an empty page in your passport for the border officer to stamp when you arrive. At least 1 blank page | Your passport must have at least 1 blank page for the entry stamp. It's wise to have more than one blank page in case of additional stamps or unforeseen circumstances. | Required |
| Return or onward ticketHaving a ticket out of the US shows you plan to leave on time, which helps avoid questions at the border. Not explicitly required but strongly recommended | While not a formal requirement for Portuguese citizens under the Visa Waiver Program, US border officers may ask for proof of onward travel. It is strongly recommended to have a return or onward ticket dated within your 90-day maximum stay. | Recommended |
| Proof of fundsYou might be asked to show you have enough money for your trip, so it's good to have proof ready. Not explicitly required but may be requested | There is no fixed minimum amount required, but you should be able to show that you can support yourself during your stay. Carry bank statements, credit cards, or cash as evidence if asked. | Recommended |
| Maximum stayYou cannot stay longer than 90 days; there is no extension option for this type of entry. 90 days | As a Portuguese citizen under the Visa Waiver Program, you may stay in the US for up to 90 days per visit. This stay is not extendable; you must leave before the 90 days expire. | Required |
| Arrival declarationYou don't need to fill out any extra arrival form before you land; ESTA is enough. Not required | No separate arrival declaration (such as an online form) is required for Portuguese citizens entering the US under the Visa Waiver Program. The ESTA serves as your pre-travel authorization. | Not required |

Transiting through United States
Portuguese citizens are eligible for the Visa Waiver Program and do not need a visa for transit through the U.S., provided they have an approved ESTA. However, if transiting to a third country, an ESTA is still required for entry into the U.S. airside transit area.
- If the traveler has been present in certain countries (e.g., Iran, Iraq, Syria, Sudan, Libya, Somalia, Yemen, North Korea, Cuba) since March 1, 2011, they are not eligible for ESTA and must apply for a transit visa (C-1) at a U.S. embassy.
- If the traveler has been arrested or convicted of certain crimes, they may be ineligible for ESTA and require a visa.
- If the traveler has previously overstayed a U.S. visa or been denied admission, they may need a visa.
