answer:There’s information available via Google @Jeruba. For instance, this site provides information about visiting North Korea. It looks to be out-of-date, but it includes the names of three people who used to organise tourist trips. If I were you, I would Google their names and check for them on LinkedIn and then I’d email them or phone them to talk about organising such a trip now. There are a couple of tour groups too. This one has information about visiting North Korea, but again, has an email address so you could write to them to find out if they can recommend anyone in the US who might be able to provide information for US travellers. Similarly, this is an Australian site. They would be able to provide information and could perhaps put you in touch with someone reliable in your own country. It depends on whether you really want to visit North Korea, or are more information about the process as a writer. Either way, the people connected to these sites would be good places to start.
