Tourism can be an economic gold mine when approached properly, and most countries around the world have embraced visitors with open arms. However, there are several places across the globe who decided that they were better without the masses of newcomers: here are 10 countries that have closed their doors to Americans and many other nations around the world.
1) Saudi Arabia
requires all visitors to be sponsored by a legal resident or citizen. Even if you’re sponsored properly, there’s no guarantee that you’ll then be awarded a visa as the application process is highly selective.
2) Iran
Iran doesn’t even have an American Embassy anymore, thanks to the tense Iran hostage situation that occurred there in 1979. If you are able to secure an Iranian visa through the Pakistani embassy in Washington, D.C., you will need to show that you’re traveling with a tour group.
3) North Korea
North Korea requires all visitors to book a full package tour before visiting. During your visit, you’ll be required to stay with your guides the entire time. The lack of North Korean embassy in the U.S. means you’ll need to travel to China before booking a tour.

4) Syria
Syria is in the midst of conflict, but if that doesn’t deter you, the nearly impossible-to-get visa might. Since each visa has to be approved through a complex process, potential visitors face an indefinite wait to be approved or declined.
5) Somalia
Somalia is known for the vast number of pirates roaming the seas around it, which should be a good reason not to go. Even if you make it past the pirates, you’ll need a sponsor and an invitation to visit the country.
6) Angola
If Angola is on your must-visit list, you’ll need to be okay with some serious expenditure before you even find out if you can go. Before you can apply for a visa, you’ll need to pay the application fee and invitation fee, then book plane tickets and hotel stays.

7) Libya
Lybia and the U.S. have been at odds for most of the 21st century, and, the U.S. Embassy closed there in 2014. Without a visa, Americans have few ways to visit this warn torn country–and that’s probably for the best because of the anti-U.S. sentiment and high crime rates.
