Do US Citizens Need a Visa to Visit Colombia?

No — as of 2026, US citizens do not need a visa for tourist stays in Colombia of up to 90 days, which comfortably covers virtually any dental tourism trip, including multi-visit treatment plans spread a few months apart (each visit simply counts as a separate 90-day allowance).

You'll need a passport valid for at least the duration of your stay, and immigration officials may ask about the purpose of your visit — having a simple letter from your clinic describing your treatment plan and dates can smooth this conversation, though it's rarely required in practice.

Colombia occasionally adjusts entry requirements, so it's worth a quick check of official guidance close to your travel date rather than relying solely on older information, especially if you're booking treatment many months in advance.

Bottom line: most US patients need nothing more than a valid passport — no visa application, embassy visit, or advance paperwork required for tourist-length dental trips.
