Yes, it's not illegal. My friend went to a good plastic surgery hospital last year, otherwise he would investigate and deal with some undocumented people, and the responsibility would still be investigated. As for the group, ostensibly under the banner of tourism, in fact, most of them go for plastic surgery. . . . I recommend Jeong Ou Ting Dong in Seoul, Korea. The streets and alleys there are plastic surgery hospitals. He went to the VIP International Plastic Surgery Hospital in Seoul, which was really good.
