The passport index, which annually ranks the world’s travel documents according to the number of destinations their holders can access without needing visa authorization, named Singapore the most powerful passport in the world.

Citizens of Singapore have access to 195 travel destinations—more than citizens of any other singular country—and 169 more than the world’s least powerful passport, Afghanistan.

Five countries are tied as having second most-powerful passports, including Japan, which is ranked among one of most difficult countries for which to obtain citizenship, according to Global Immigration Services.

Prospective citizens must live in Japan for five years before they become eligible to obtain a passport, must pass a Japanese language test, must prove they’ll be able to make a living in the country and are forced to renounce any previous citizenship—and the process can take months or years to wind through Ministry of Justice procedures after the requirements are met.

Seven countries were ranked by Henley as tied for the third most-powerful passports in the world, and two of those were also among the most difficult to obtain—Austria and Finland.

Austria requires a decade of continuous residency or five years of marriage to an Austrian, a language test and renouncing previous citizenship before naturalization is considered—or people can apply through the citizenship by investment option, which allows applications from those who have made significant economic investments in the country.

Finland’s process can take years to complete after the requirements are met, which includes proficiency in Finnish or Swedish, five consecutive years of residency, a clean tax payment record and proof of financial stability.
