If you don't go through the formalities of suspension, you can't go through the formalities of suspension, and the files are naturally still at school. Another possibility is that the school will go through the withdrawal procedures for you according to the automatic withdrawal treatment, and the files will be sent to the students.
Your best way now is to call the school's student status file management department to find out if the file is in the school. If you need to go back to school to go through the formalities of dropping out of school or leaving school, the files can only be transferred back to the place of origin. If the school has transferred the files back to the source of students, please provide the specific address when inquiring.
