Direct answer
A wedding invitation does not create a separate entry route in the U.S. and UK government guidance used here. U.S. citizens and British-citizen passport holders should check the rule that matches their nationality and travel plan, then keep entry permission separate from the couple’s municipal marriage process.
The current U.S. guidance says U.S. citizens do not need a tourist visa for stays of 90 days or less and should have a passport valid for at least three months beyond the planned departure from the Schengen area. GOV.UK says British-citizen passport holders can travel visa-free in the Schengen area, including Greece, for up to 90 days in any 180-day period, subject to the stated passport rules.
The traveller’s audience changes the check
| Traveller | What the current official guidance supports | Do not infer |
|---|---|---|
| U.S. citizen visitor | No tourist visa for a stay of 90 days or less, subject to the U.S. guidance’s stated passport and border conditions. | That visitor entry authorises a municipal marriage process. |
| British-citizen passport holder | Visa-free Schengen travel, including Greece, for up to 90 days in any 180-day period under the stated conditions. | That a wedding invitation fixes the permitted stay or replaces border requirements. |
If the guest is a U.S. citizen
The U.S. Department of State’s Greece guidance says U.S. citizens do not need a tourist visa for 90 days or less. It states that a passport should have at least three months’ validity beyond the planned departure from the Schengen area. It also says travellers may be asked to show a return or onward ticket and evidence of funds.

If the guest is travelling on a British-citizen passport
GOV.UK says that a British-citizen passport holder can travel without a visa to the Schengen area, including Greece, for up to 90 days in any 180-day period. It also says a traveller may need to show a return or onward ticket and prove they have enough money for the stay.
90 days in 180 Count time spent in the whole Schengen area, not only time in Greece.
Before a guest travels
- Read the current U.S. State Department Greece guidance or GOV.UK Greece entry requirements close to departure.
- Check the traveller’s passport validity and any transit-country requirements.
- Keep any return or onward evidence and funds evidence accessible if the source says it may be requested.
- Keep the visitor-entry check separate from the couple’s municipal marriage route.
- This guide does not cover work, residence, visa extensions, or a nationality other than the named audiences.
For the legal ceremony route, start with the Greece municipality-first guide. For the country overview, see planning a wedding in Greece. A guest-entry check does not answer where a marriage record is registered; see Greek marriage registration and certificates. You can also start a private planning checklist.
