When going to Seoul for a performance, will language be an issue?

Hello! My name is Uyanga from Mongolia. I'm planning to visit Seoul at the end of this year for cosmetic surgery, but I have one concern — do you think the language barrier will be a problem?

I speak Mongolian fluently, but my English isn't very good. Do Seoul clinics that perform cosmetic procedures have Mongolian translators? Or is English sufficient for understanding basic things? Has anyone been there before, and did they have any language difficulties during their procedures? Are there any rules or good tips?

I'm hoping that if I do my research well before getting the surgery, and if my language skills are decent, it won't be too much of a hassle. Has anyone shared their experience with this?
