1. It is necessary to provide transcripts, diplomas and no criminal record (both in Chinese and one in English) to the police station where the household registration is located.
2. The second is fairness. You need to submit your three documents to the notary office. You can translate it yourself or go to the notary office for translation. Of course, translation costs money. If you do it yourself, sometimes it is not recognized. Some notary offices will look at your form. If it is inconsistent with others, be sure to let them translate. It takes about a month.
3. Get a passport and 250 yuan will do. Go to the local exit-entry management center and you can get it in half a month.
It would be nice if these total expenses were reduced to a little over two thousand. No intermediary is needed. It's simple.
If you still want to know, leave me a message and I'll try my best. I hope you will succeed in studying abroad.
