I applied for studying in the Netherlands, and the admission notice was February 1, but I haven't received the application notice yet.

Generally, when you go to study in the Netherlands, the school will directly help you submit the application for mvv in the Netherlands, and then the Dutch Immigration Bureau IND will send you a notice to get a visa at the consulate in China. Although the efficiency of IND is generally low, the visa processing cycle is generally only 4-6 weeks if students are given a fast mvv (nuffic certificate is required). I wonder when your school handed in the application. Now that school starts, you will definitely miss it. However, you can ask your school to consult IND about the processing progress and the study arrangement after you arrive in Holland.
