my parents want to attend the graduation ceramony. but our school is not giving invitation.

Hi, no objection letter may be not enough for visiting visa. But your parents can apply for S type which requires documents include their passports, visa application form and photo, your invitation letter, original and copy of your passport and china residence permit, original and copy of your birth certificate.

The problem is my mother is coming with my cousin, because my mother haven't been outside before country and she don't have much knowledge about flights and terminals. specialy in china its hard to find everything it can confuse her. so my mothers is coming with my cousin. do you know any one who can help in this situation?
