What should I do if the Sany registration materials are not signed?

It is recommended to contact the school enrollment teacher to see if there are any supplementary materials or other methods.

If the registration materials are wrong and need to be corrected, you can apply for revision online or contact the relevant college admissions staff during working hours. The specific contact information can be found in the admissions brochure.

If you stamp the school's seal, it means that these materials have taken effect, because many materials are submitted by yourself. The materials you submit prove that your school will review the materials you submit, and stamp them if there is no problem in the review.
