Where can you go?

Passport strength refers to how many countries a passport holder can visit without obtaining a visa in advance. It is measured by counting the number of destinations offering visa-free access, visa on arrival, or electronic travel authorisation (eTA) to holders of a given passport.

As of 2026, the Singapore passport scores highest in our index, with visa-free, visa-on-arrival and eTA access to 159 destinations combined. See the full ranking, including how e-visas are tracked separately, at /rankings.

Yes. Holding a valid US visa (B1/B2 tourist or business visa, or a US Green Card) unlocks additional visa-free or visa-on-arrival access to dozens of countries including Mexico, Costa Rica, Guatemala, and Albania - destinations that may otherwise require a visa for your nationality. The exact list depends on your own nationality, since these rules are scoped per passport, not universal.

Visa-free access means you can enter a country with just your passport - no advance application, no fee, no paperwork at the border. Visa on arrival means you receive an entry stamp or sticker at the airport upon landing and pay a small fee there. Both allow entry without pre-arranged appointments at embassies or consulates.

Earth Visa sources visa policy data exclusively from official government sources - foreign ministry pages, border authority portals, and published bilateral visa agreements. Each entry links to its official source. Data is updated continuously. Where governments do not publish structured visa-free lists, we do not extrapolate - so reach counts are conservative lower bounds.
