You are eligible for visa free entry
Must be valid throughout your stay and for at least 3 months beyond your planned departure from the Schengen Area. A damaged cover or unreadable chip will cause delays at passport control. Keep it in proper shape before you travel.
Argentine passport holders enter Greece and the entire Schengen Area without a visa. Nothing to apply for, no fee, no pre-approval required.
Border officers can and do ask for proof that you're leaving. A confirmed return flight or onward booking satisfies this - Travelling on a one-way ticket without proof of onward travel may increase the chance of additional questions.
Schengen rules allow officers to ask whether you can support yourself financially during your stay. A bank card with accessible funds or a recent statement generally covers it if the question comes up.
Not guaranteed to be asked, but having a hotel booking or a host's address ready keeps things moving smoothly at the counter.
Direct flights are generally not common, and most travellers connect through hubs such as Madrid, Frankfurt, Istanbul, or Amsterdam. Total travel time typically falls between 18 and 24 hours, depending on the layover. Iberia, Lufthansa, Turkish Airlines, and KLM are the most common carriers on this route.
Argentine citizens can remain in the Schengen Area for up to 90 days within any 180 days. This isn't per country - it's across all Schengen member states combined. Track your days carefully if you're moving through multiple European countries.
A tourist entry covers neither. If your plans go beyond leisure travel, contact the nearest Greek consulate or embassy before you leave and arrange the correct visa category in advance.
