4. North Korea
It is a well-known fact that North Korea and South Korea are not on a friendly basis which explains military fortification along the 150 miles-long border between these two countries. No need to say that border control is more than strict in one of the most authoritarian countries in the world. The process of entering the country is pretty much the same except the customs which are very strict especially in terms of electronics you want to bring in. It is not uncommon that customs officers ask to inspect your phone, laptop content and photos on your camera. Photos are checked especially once you decide to leave the country and you might be even asked to delete some questionable photos. When entering the country you are not allowed to own any anti-North Korea materials.
