"Complicated" Countries To Visit

An article in Budget Travel claims to reveal the 8 Most Complicated Countries to Visit. What the writer is actually describing are countries for which one has to apply for a visa in advance, a process that may be expensive or time-consuming or both. We've already visited (or are planning to visit) four of the eight: India, Russia, China, and Brazil. It's doubtful we'll visit the other four but more adventurous folks might want to. Read the list and decide for yourself. Finally, there was one obvious and glaring omission from the list. Can you guess? It all depends on your perspective.
