Depends what procedures you are trying to do. For breast augmentation or if you want to get only eyelids done, I would just stay in the US.
I agree that rhinoplasty is one of the more difficult surgeries to perform. However, I decided to go to korea because doctors here are specialized. Most surgeons in the US are what i would call a "jack of all trades" meaning they perform all different kinds of surgeries. Asian patients also make up a smaller percentage of the client base in USA. Asian rhinoplasty is completely different from caucasian rhinoplasty. For these reasons, I chose to go to korea because I wanted to a doctor who specializes and has a lot of experience with asian rhinoplasty.
I went to a high end clinic in Korea that caters to foreign patients. I had 1-2 translators with me the whole time and their communication skills were excellent. They are on the expensive side, so I didn't really save any money lol. When I take flight and accommodations into account (~$2000), I spent just as much (or maybe a little more) than I would have paid in the US. I have also gotten plastic surgery in the US and the experience in Korea is different. There are definitely some benefits to getting your surgery done in the US instead. Since I am only one week post-op, (just removed all my stitching and bandages today), I will hold off on my opinion on whether it was worth it or not since I will be seeing more changes as I heal.
