United States entry requirements for Slovenia passport holders
Slovenian passport holders can travel to the United States for tourism or business for up to 90 days without a traditional visa, thanks to the Visa Waiver Program. You must obtain an approved ESTA online before your flight. This requirement applies in 2026.
Entry requirements
| Requirement | Details | Status |
|---|---|---|
| ESTA (Electronic System for Travel Authorization)You need an approved ESTA before you fly to the US; without it you will be denied boarding. Visa waiver entry | Slovenian citizens must obtain an approved ESTA before boarding. Apply online at the official ESTA website (https://esta.cbp.dhs.gov/). The cost is US$40.27 ($4.00 processing + $36.27 authorization). Processing is often instant, but allow up to 72 hours. The 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 6 months after your planned departure from the US. Valid for 6 months beyond stay | Your Slovenian passport must be valid for at least 6 months beyond your intended stay in the United States. | Required |
| Blank passport pagesThe US border officer will stamp your passport; you need a blank page for that. At least 1 blank page | Your passport must have at least 1 blank page for the entry stamp. | Required |
| Return or onward ticketHaving a return ticket helps show you are a genuine visitor and plan to leave on time. Recommended | Although not always checked, it is strongly recommended to have a return or onward ticket to prove you will leave the US before your 90-day stay expires. | Recommended |
| Proof of fundsYou may be asked to show you can pay for your trip; having proof helps avoid issues. Recommended | Carry evidence of sufficient funds for your stay (e.g., bank statements, credit cards). No specific amount is required, but you should be able to cover your expenses. | Recommended |
| Arrival declarationYou do not need to fill out any extra arrival form beyond the standard customs declaration. Not required | No separate arrival declaration is required for Slovenia citizens entering the United States under ESTA. | Not required |
| Visa extensionYou cannot stay longer than 90 days; if you do, you risk overstaying and future visa problems. Not permitted | The 90-day ESTA stay cannot be extended. You must leave the US before the 90 days expire. | Not required |
