This article states that a NK defector walked into a U.S. Consulate in Moscow to seek refuge:
It has been confirmed that the man went to an influential local newspaper to ask for help, saying that he did not want to go back to North Korea, a week before he entered the U.S. Consulate. But the paper refused his request, after which he entered the Consulate. This is the first time that a North Korean has entered a foreign legation in Russia.Some 12,000 NK workers in forestry, agriculture and construction across Russia are also seeking refuge, but are having a difficult time to do so:
[...] [I]t is not easy for them to seek refuge because they live in a systematically monitored group, are very loyal to their communist country and most of them have families in North Korea.As evident, this leaves many NK refugees in a predicament, and at the same time, it is difficult to decide what it is that can be done to provide a solution to this issue.
