The University of Salamanca is one of the oldest in the world and today it continues to be one of the most powerful in the world, especially in Letters and Social Studies. It also has agreements with many foreign universities, which can greatly facilitate any type of exchange (believe me that in these things, the paperwork can be endless and if it’s already done, even better).
On the other hand, it is necessary to say that the city of Salamanca is one of the best to spend your university stage. Most of the people you will meet will welcome you with open arms.
