Change from student visa to Q type after getting married

Hey!
I'm married to a Chinese recently (we've been together 4 years now). Currently I have a student X type but I've just graduated and it will be due on July the 20th, but I will go back to my country on July 15th, I plan to come back at the end of August. Is it possible to change my student X type to a Q type while I'm still here? If so, what do I need? I know I need my passport and its copy, photo, application form, marriage certificate, health certificate, my husband's ID... am I forgetting something? I would really appreciate you help since I've got not much time.
