Not all schools are considered to be official schools. The ministry of education requests universities and research centres to comply with a series of requirements . In this way the country can control what subjects are offered in each center and what is the level reached by students while pursuing the course.
One of the requirements while obtaining a student visa or to renew a student permit is that the course will be held in an official center. It is very important to ensure that the center is official before making the payment of the reservation of the course, as most centers do not return the inscription amount except in very specific cases.
If you want to know if the study center where you want to register is official, you can consult the center itself or send us an email and we will give you an answer.
