I’m Asian, and I have friends who have had surgery in Korea and recommended it. I personally could not imagine traveling
To a foreign country; dealing with the many issues via translator; and not recovering at home. Aftercare is extremely important to me, and I prefer it to be local. It is also important to me that the surgeon and I be on the same page re aesthetics,* and I strive for seamless and open communication. That would be more difficult with language constraints. I would also like to recover in my own place. ETA: I also very much value my relationship with a doctors office staff bc it affects how I feel generally; as well as the level of care and service. I am used to the style of warm and professional service that I find locally.
I wouldn’t make a generalization, and I assume that there are excellent surgeons in many places, but my experience: upper bleph; fat graft; fat removal under the chin. I also had another procedure months later: wet lipo in mid section and under armpit. Both were outstanding experiences. Not inexpensive, but if I had to economize, my face anbd bod6 would not be places to start. Another close member of my family has done more complex procedures, and a dear friend also gave a glowing report. My results are beautiful, yet subtle enough that my own mom assumed that changes were due to weight loss; exercise; and lack of stress. She is not the most observant, and I wea4 glasses, but still lol.

My personal trainer (one of my best friends) and others who are used to scrutinizing my face and body regularly (like SAs) had similar reactions.
ETA: certifications are important; but so are the number of procedures done; and the accessibility of the Dr. post surgery. I was told in no uncertain terms to contact the office and my dr directly, (patients are given his personal cell) at any time, with any issues. And. I have always received prompt responses. In fact, he often lectures internationally, and I have received responses even when he is across the country; in South America; or elsewhere.

ETa: there is a strong difference between east coast and west coast philosophies of plastic surgery. East coast is considered to be more subtle; this should factor in your decision.
