The strength of a passport for obtaining travel visas can be measured by the number of countries that passport holders can visit without requiring a visa or by obtaining a visa on arrival. The following countries’ passports are considered strong for visa-free travel or visa-on-arrival access to many countries:
* Japan
* Singapore
* South Korea
* Germany
* Italy
* Finland
* Spain
* Luxembourg
* Denmark
* Austria
It’s important to note that passport rankings can change over time due to visa policy updates, geopolitical factors, and international relations. Additionally, visa requirements and policies can vary for specific nationalities, so it’s always advisable to check the visa requirements of the country you plan to visit before your trip, regardless of the strength of your passport.
