How do foreigners find a reliable clinic in Korea?

Hello! I'm Khulan from Mongolia. I'm thinking of getting cosmetic surgery in Korea this fall, and there are a lot of clinics these days. But with so many choices in the capital, how do foreigners actually find a reliable clinic to choose from? What criteria do you generally use to start your search?

Especially, the language issue is very important during the consultation. How do you check if there is an interpreter or if the doctor speaks English? I myself am very nervous, and it would be better if I went to the consultation with an interpreter. I don't know what kind of questions to ask. What did you do when you first started?

Any advice or experience would be appreciated! It's nice to hear the opinions of real foreigners, even if it's just a matter of choosing based on the exhibition and the Internet. Thank you!
