This question was recently migrated to Politics.SE from Law. In substance, the question asks where North Koreans traveling in the United States can receive consular services.
Since it is a question of diplomatic policy it is definitely on topic here. However, it's been on our site since November (2+ months) without an answer.
Should we migrate it to Travel.SE? I hate to pass the question off to another Stack (again), but I'm also wondering if experienced world-travelers might know a better way to answer the question than the folks here.
