Has anyone consulted in Seoul who only speaks English or Vietnamese?

Hello everyone, I'm Nga from Vietnam. I'm considering getting some procedures done in Seoul but I'm a bit worried about the language barrier. I can speak English, but not very fluently, and I don't know any Korean at all 😅

Has anyone consulted there before? I'd like to know if the clinics there have English-speaking doctors or staff, or if I should look for a tour company/translator to assist me. I'm afraid it might not be safe if I don't fully understand my health concerns.

Another question is, if I don't speak Korean, will there be any difficulties in the follow-up process (check-ups, Q&A afterwards)? I'm seeking advice from those who have experienced it. Thanks a lot! 💕
