Hi,
There are many colleges across the world that have very less or no tuition fees. You can apply in those colleges or universities.
Some of those universities are:

Halmstad University, Sweden
University of Copenhagen, Denmark
University of Oslo, Norway
Uppsala University

Choose the right degree. Some universities provide scholarship for specific degrees. For instance you are more likely to get a scholarship for an MS than for an MBA. In absolute terms a 25% MBA scholarship at a top business school is equivalent to a full scholarship in many MS programs.

Your GRE, GMAT, SCAT, ACT scores matter a lot. The higher you score the more the possibility of getting a good scholarship. English proficiency exam scores are also important for admissions.
Hope it will help you!
