Before graduation, Cuban schools will inform students to buy a tax ticket (I remember it is 40CUP) in advance and give it to the school. The school will take it to the Cuban Ministry of Higher Education for notarization and go to the Cuban Ministry of Foreign Affairs for certification. Upon completion, I will teach you the original diploma and notarized copy (two copies) when you graduate. This was made by the ancients.

After that, you go to the Consular Section of the China Embassy in Cuba, and use the copy for consular certification (this is for your own use, so you can omit this step). Bring the original graduation certificate, passport and student ID card in Cuba to the Cultural Office to issue the certificate of returning overseas students (in triplicate, one for the Cultural Office, one for yourself, one for returning to China, and the last two for you to take with you). You are a public student, right? Maybe your card will be opened by the school assistant, and you don't have to go to the embassy to get it, because there are too many of you. ...

After returning to China, go to the Education Certification Department (Beijing is a service center for overseas students in Beijing) and certify with the original diploma, a copy of the diploma (copied by yourself), a translation of the diploma (translated by a qualified translation company, don't send it directly by yourself), certificates of overseas students, ID cards, passports and photos. The original graduation certificate, ID card and passport will be returned to you after inspection, and other materials will be kept by yourself. Tell you when to get it. I remember about a week, so I can get their certification certificate (with steel seal on it). This certificate is a sign that the domestic education department recognizes your academic qualifications.
