What is the minimum number of passports needed to enter every country in the world?

The minimum number of passports needed to enter every country in the world is two. These two passports belong to the citizens of the only two countries in the world that have unrestricted access to all other countries. These two countries are the United Kingdom and Sweden.

The United Kingdom passport allows its citizens to enter 166 countries without a visa, and the Swedish passport allows its citizens to enter 165 countries without a visa. This means that if a person holds both of these passports, they can enter all 195 countries in the world without needing a visa in advance. However, it's important to note that some countries may require a visa upon arrival or may have other entry requirements that must be met.

As of March 2023, the minimum number of passports needed to enter every country in the world is 9. This is because there are 199 countries in the world, and there are 9 passports that grant visa-free access to all of them. These passports are from the following countries:

• United Arab Emirates
• Japan
• Singapore
• South Korea
• Germany
• Italy
• France
• Spain
• Portugal

It is important to note that this is just a theoretical minimum. In reality, it may be difficult or impossible to obtain all 9 passports. For example, some countries have strict requirements for naturalization, and it may take many years to become a citizen. Additionally, some countries may not allow dual citizenship, so you may have to give up your current citizenship in order to obtain a new one.

If you are interested in traveling to every country in the world, it is important to do your research and plan ahead. You will need to make sure that you have the necessary visas and that you are familiar with the immigration laws of each country. It is also a good idea to have a backup plan in case something goes wrong. For example, you may want to carry a copy of your passport with you at all times, just in case your passport is lost or stolen.

Traveling to every country in the world is a challenging but rewarding experience. With careful planning and preparation, it is possible to achieve this goal.
