First of all, CSC is generally aimed at students from Boyi to Boyi, and the duration of going out ranges from 6 months to 2 years. The state grants subsidies according to certain rules (depending on countries and regions).

The process is to get the invitation letter from the other school first, then apply to your own school (the school organizes the application every year), and the school submits it to the state for approval and finally gets it.

Generally speaking, this kind of public school is an exchange visit and does not take the degree of the other school. Getting an invitation is relatively easy. The usual process is to write an email directly to the tutor of the other school, introduce yourself, and declare that the expenses will be paid by yourself, not the other party's money. If you are in the same direction as the other party and your own conditions are ok, it is easier to get an invitation. Another way is that your tutor has someone familiar with you in a foreign university, which makes it easier to get an invitation letter.

There is also joint training, and both sides have degrees. This needs to be based on the other party's admission requirements, such as TOEFL IELTS GRE and other scores. The process is relatively complicated and much more difficult. This is usually because the two schools have cooperative projects or have a hard relationship.
