To apply for foreign graduate students, you need to submit the original double certification. Generally speaking, students applying for graduate students in foreign universities need to submit degree certificates, transcripts and other materials, which require double certification. Specifically, the academic affairs office of students' alma mater needs to issue a degree certificate and transcripts, which will be certified by the Ministry of Education or Chinese embassies abroad. The purpose of certification is to prove the authenticity and validity of these materials in order to be recognized and accepted by foreign universities.

It should be noted that different countries and schools may have different requirements for certification. Therefore, before applying for foreign graduate students, students are advised to read the requirements carefully and understand the documents and authentication methods that need to be provided. If in doubt, please consult the Admissions Office of the target school or relevant institutions so as to prepare and submit the application materials as soon as possible.
