[코성형] I am planning to get rhinoplasty for an overseas resident.

I'm currently living overseas and I'm thinking of coming back from Korea to get rhinoplasty, but I don't know what to do first. First, I sold my handmade items and wrote down a list of about 15 items, but I wonder if that's enough. I don't know if I should make a reservation here in advance and go to Korea, or if I can go in and make a reservation a few days in advance, they will accept it. If there is anyone like me, please let me know a tip or something. I'm worried that I might come back and get sick. Would it be okay if I just wait for a month to see how it goes and then come back? It's very difficult..!!
