Native speakers do not have to prove their language ability.
Chinese: We accept language certificates for HSK 5 and TOCFL 4 or higher.
Japanese: We accept language certificates for JLPT 2 or N2 and higher.
Korean: We accept language certificates for TOPIK 4 and higher.
HSK 4 or a master’s degree in Chinese, Japanese or Korean studies are sufficient only when you have been abroad for about a year, have been active in translation, or possess other additional language skills. We recommend an actual assessment by a language teacher or language centre if you cannot provide a certified language proficiency.
