To apply for a student visa you will need to provide a letter of confirmation from the university in which you will be attending. This will need to be presented when applying for your visa.
Student confirmation letters will need to be written by officials from the university where you will be studying.
In addition, you may also need to provide proof of residency for university residence, proof of finances to make sure you have enough money to see you through the duration of your stay and in some cases proof of medical insurance.
It is always advisable to contact your intended destinations' embassy for further information before applying for visas either through a passport agency such as ourselves or through embassies themselves. This reduces the risk in getting rejected for your application.
