At the passport desk of an Athens airport, the officer glances at your photo page, stamps it, and the Aegean holiday you have been planning for months begins.

What do you need to enter Greece?
U.S. citizens need a valid passport and may enter Greece without a visa for stays of up to 90 days for tourism or business purposes. That covers a typical tourist stay.
Two things can be asked of you at the desk. Officers may ask for proof of sufficient funds and a return airline ticket, or other evidence that you will leave. The funds requirement is often met with credit cards. Keep your onward or return booking where you can reach it, since that is the document an officer may want to see.
A passport reported lost or stolen
A passport that has been reported lost or stolen is not accepted at the border, even if you find it again afterward. U.S. citizens traveling on such a passport will not be permitted entry into Greece and may be returned to their original departure point.
If you lose your passport once you are already in the country, emergency passports for U.S. citizens are issued only at the Embassy in Athens. Embassy staff do not travel to air, land or sea ports of entry, so a replacement means getting to the capital. That matters if you are on a remote island when it happens.
Passports that list Macedonia as the place of birth
A few travelers will notice something different at the desk. If your passport lists your place of birth as the Northern Republic of Macedonia, Greek authorities will stamp the passport upon entry in the usual way.
If it lists Macedonia or the Republic of Macedonia, Greek Immigration officers at ports of entry (land, air and sea) will not place the entry stamp directly in your passport. Instead you complete a short form, keep it with your passport while you are in Greece, and present it when you leave.
Losing that form creates a real obstacle. You must visit a police station and file a report before Greek authorities will permit you to depart the country. Keep it tucked into the passport for the whole stay.
Official, diplomatic and military travel
The visa-free rule is for ordinary tourist passports. Holders of U.S. official and diplomatic passports must obtain a Schengen visa before arriving in Greece, and without one they will not be allowed to enter.
U.S. citizens traveling on official military orders to Greece should review the guidance in the Department of Defense Foreign Clearance Guide. Health status plays no part in entry: the U.S. Department of State is unaware of any HIV/AIDS entry restrictions for visitors to or foreign residents of Greece.
How long must your passport be valid?
The U.S. State Department recommends at least three months of validity beyond your planned departure date for entry into Greece, although Greek law requires only three months beyond the intended departure date. The two figures are different, and the gap between them is where travelers get confused.
| Source | Remaining validity |
|---|---|
| Greek law | Three months beyond the intended departure date |
| U.S. State Department recommendation | At least six months |
Which figure to plan around
The legal minimum is counted from the day you plan to leave Greece, not from the day you arrive. A passport that expires in the autumn could be fine for a spring arrival and still fall short if your trip stretches long enough to push the departure date close to the expiration.
The six-month recommendation is the safer yardstick when you are deciding whether to renew. If your passport is near that mark, renewing before you book flights removes any doubt at the check-in counter or the border desk, and it costs you nothing in flexibility.
Checking your passport before booking
Look at the expiration date on the photo page and count forward from your planned departure from Greece. If you are combining Greece with other countries, count from the last day of the whole trip, since each border may apply its own rule.
Also check that the passport is not one you have reported lost or stolen. A replacement issued after a report is a different book, and the old one will not be accepted if it turns up again. Carry the one you actually have in hand, and travel with the same passport you used when you booked.
If something goes wrong abroad
A damaged or lost passport during the trip is handled in Athens, where the Embassy issues emergency passports for U.S. citizens. Since staff do not come to ports of entry, plan on traveling to the capital with whatever identification you still have. A photocopy or a photo of the passport page kept separately from the passport itself is a habit that makes the paperwork in that situation less painful.
Good to know before you go
The U.S. State Department rates Greece Level 1: Exercise Normal Precautions.
Keep the passport with you through the whole trip, along with the entry form if you were given one, since both come into play again at departure. A credit card in your own name also helps if an officer asks about funds. Greece in summer can be hot, and in the Aegean a strong wind called the meltemi sometimes blows, so build a little slack into travel days.
