Is it permissible to work in a medical center during the امتياز year and before obtaining a work permit, knowing that the student possesses certain skills and not others, and that the wage is meager, and is the earning in this case considered halal?

The law mandating a year of internship for professional practice must be respected, and violating it is forbidden, as it prevents harm to people and blocks those who would exploit the system. Therefore, it is not permissible to continue in this work. As for the earnings acquired from it, they are permissible as long as they were in exchange for a well-executed work.
