VISA and Travel Documents

Greece, a member state of the European Union and part of the Schengen area, operates under a unified jurisdiction for international travel, facilitating seamless movement without border control within the area. The visa policy for the Schengen Area is established by the European Union. Non-EU, non-EEA, or non-Swiss citizens must possess a visa or be from a visa-exempt country to enter. In order to visit Greece you need to have the following travel documents:

  • ID card. In the case that your country of origin is a signatory to the Schengen Agreement, you may use your national ID to enter the country and you may stay for a three-month period. In these cases a passport is not necessary, although you will need it in a variety of other transactions, including currency exchange, shopping etc.
  • VISA. If your country is not a member of the Schengen Agreement, a visa is required for visiting Greece, applications can be made through the Greek Diplomatic Mission or Consular Post in their respective country. If unavailable, contacting any Schengen Area member state's Consular Post suffices. Notably, a visa issued by one Schengen member state is valid for all others, enabling travel across multiple countries within the area. For more details you can visit the Hellenic Ministry of Foreign Affairs portal. Should you require a letter of invitation or additional documentation for visa application, kindly utilize our contact form after payment of the registration fee.
  • Passport. If your country of origin is one of the following non-EU countries, your passport allows you to visit Greece and remain in the country for up to three months (90 days) within a six-month period: Andorra, Argentina, Australia, Brazil, Brunei, Canada, Chile, Costa Rica, Croatia, El Salvador, Guatemala, Honduras, Israel, Japan, Malaysia, Mexico, Monaco, New Zealand, Vatican, Nicaragua, Panama, Paraguay, San Marino, Singapore, South Korea, USA, Uruguay, Venezuela. Find out more on the official webpage of the Hellenic Ministry of Foreign Affairs.
