can i get student visa for macau..?i am from nepal

You can get a student type for studying there or get a work type for working there. You cannot work with student type.

For applying a student, you need to have a admission letter from a college in Macau. Then you need to use your valid passport, application form with recent taken photo, bank statement or any other types of financial proof, returning flight ticket (if the course is less than 6 monthes) together with your admission letter to apply through local Chinese embassy.
For working, you need to provide the application form, passport and employment approval document issued by the Macao authorities to apply.
