North Korea Guide
Entry Requirements
Everyone needs a visa to enter North Korea, and though the process of obtaining one is lengthy, as long as you've got money and make your plans a couple of months in advance you should find it pretty easy to get in. Those from the "wrong countries" (ie USA and Israel) are allowed in occasionally, most often during the Mass Games period. Journalists can also find it hard to get in, though again it's not impossible – it's the travel agency's responsibility to vet applicants, so if you say that you're a circus freak and they believe you, you're in. Many try to avoid fraud by asking for signed confirmation from your employer.
Your visa is organized prior to arrival by the travel agency and forms part of your tour price. It comes on a slip of paper (not as an insert in your passport) that you'll only possess for a short time on entry to North Korea. You won't receive a stamp, so there'll be no evidence of your visit in your passport.
It's wise to have travel insurance wherever you go, and North Korea is no exception. Most travel policies cover North Korea, but do check by making a quick call to your company; if they won't cover you, find one that will.
