Travelers do not need a visa for Business or Tourism stays up to 90 days. Travelers need a visa for longer stays.

The EU Entry/Exit System (EES) is a new digital border process for non-EU nationals traveling for a short stay (up to 90 days within 180 days). No advance action is required.

Travelers should allow additional time at passport control, especially during busy travel seasons. At passport control, travelers provide a facial photo and/or fingerprints. Passports are no longer stamped. Self-service kiosks may be available at some airports and border entries.

Travelers under 18 who are traveling alone are advised to carry a consent letter from a parent or legal guardian. The letter should include a copy of the child's birth certificate and a copy of the passport of the parent or legal guardian. If the child's surname differs from that of the parent or legal guardian, it is also recommended to include a copy of the parents' marriage certificate.
