Hello, I am a Turkish citizen visiting Macau at the moment.. I register to Jinan University Zhuhai Campus to study 1 semester chinese (less than 180 days). Several questions :

1) X1 student type, is possible to apply for multientry? (I have 3 Chinese one previously)

2) In Macau, can I apply to the consulate by myself or need an agency?

3) what is the cost of application ? or where I can get some information about it?

4) How long it takes to get my passport back ? or where I can get some information about it? Thanks!
