I think I was kinda lucky that I could visit there with my Polish friend and she managed to break the language barrier. When I visited there, most of the workers couldn't use English that well, but tried their best to support me. Thanks to this organization, I was able to get the duplication of my visa(I lost my passport with std visa in other country). If you recognize your purpose of visit and find the relative office, you don't really need to wait in a queue.
