The Schengen visa is the most common visa for Europe. It enables its holder to enter, freely travel within, and leave the Schengen zone from any of the Schengen member countries. There are no border controls within the Schengen Zone.
However, if you are planning to study, work, or live in one of the Schengen countries for more than 90 days, then you must apply for a national visa of that European country and not a Schengen Visa.

You will have to present several documents at the Schengen port of entry, in order to be permitted to enter, if you are a non-EU/Schengen country national, regardless if you are a visa-exempt or not.
