A student visa best translates into a genuine authorization the government of the designated country issues to students who are already accepted at a certified educational establishment. The holder of this type of visa is not required to have the citizenship of the designated country in order to follow studies yet it is no immigrant visa either. Every student with the citizenship of a country that requires a visa to enter the Schengen zone must obtain a student visa in order to follow studies in the educational institute of the designated Schengen country.

The Schengen visa is commonly valid for stays no more than 90 days. For the students who are planning to study in the Schengen country, it is mandatory to apply for a residency permit at the appropriate authorities. Commonly, you apply for the residency permit after you arrive at the Schengen country with the Schengen visa.
The great thing about the residency permit is that it allows you to freely travel throughout the whole Schengen area, without any additional documents needed. The residency permit is stamped in your passport. The Schengen visa validity is predetermined by the authorities the day you are issued the visa. As aforementioned, as a student visa it commonly encompasses duration of up to 90 days, with multiple-entries, however that is no rule. During that time, students are allowed to travel in and out of the designated country, within the Schengen area. However, you have to notify the authorities if you intend to make trips in and out of the Schengen space.
