Can language be a barrier to Seoul's mental health services?

Hello! I'm Naran from Mongolia. I'm planning to exhibit at an exhibition in Seoul this month, and I'd like to have a consultation before participating in the traditional exhibition. I'm interested in services that help with speech and articulation.

What I'm most interested in is speech training. While I can communicate relatively well in English, my Mongolian speaking skills haven't improved much. For the consultation, will English be sufficient, or is there a Mongolian speech therapist who works well? I'm particularly interested in anyone who has experience or recommendations for language learning materials.

Have you met people who have come for Mongolian speech therapy services, or do most people speak English better than the services in big cities? Sometimes, the description gives the impression that speaking is optional, but based on my local experience, I'm interested in enriching the materials when it comes to language acceptance. Is there a reinterpretation of the press or a square that caught your interest? I'm interested in this because I think it's important.
