According to official statements, the K visa requires applicants to have graduated from a renowned domestic or international university or research institution with a bachelor's degree or higher in a STEM field, or to have engaged in relevant professional education or research work at such institutions. Each entry under the K visa permits a maximum stay of 180 days. It offers multiple entries over a period of up to five years without requiring sponsorship from a domestic employer or inviting organization. Holders may engage in activities related to education, science and technology, culture, entrepreneurship, and business.
Note that the Chinese government has yet to announce which specific universities or research institutions qualify, a point that has caused unease among Chinese citizens.
