As a type of foreign investment company that has been doing a lot recently, a customer who has never entered Korea wanted to invest in Korea and establish a corporation, so it was carried out with a power of attorney. At first, we consulted a lot about whether to establish a liaison office by investing in a Chinese company or establish a branch office, but since it is a profit-generating industry in Korea, we decided to establish a foreign-invested company. It took about a month and a half to get a Korean consular certificate from China to establish a corporation, and it took about two weeks to get a visa, so it took a total of two months. If you establish a liaison office or branch office, you can apply for a D-7 visa, and if you establish a foreign-invested company, you can apply for a D-8 visa. In the case of this person, there were not many necessary documents because he would do wholesale, retail, and trade business in Korea.
