Visiting the US: Slovak citizen → United States
✅
No visa needed — travel on an ESTA
Slovakia is a Visa Waiver Program country, so its citizens can visit the US for tourism or business for up to 90 days with an approved ESTA instead of a visa.
The bottom line
- Apply online for an ESTA before you travel — it is electronically linked to your passport.
- The Visa Waiver Program covers stays of 90 days or less; for longer or other purposes you need a visa.
- An ESTA authorizes travel, not entry — a CBP officer decides admission at the port of entry.
Where you'll apply
The ESTA is applied for entirely online — there is no embassy interview.
