The title says it all. To elaborate, In Sweden Ph.D. is being considered a formal job and students receive a monthly salary and pay taxes. Therefore, the question is specifically about whether applying and pursuing an MBA in parallel with pursuing Ph.D. is legally feasible or a special type of permission is required from the university?
Update 1: I'm aware that it's not recommended to pursue these two demanding degrees together. The question is whether in Sweden it's technically possible or not.
Update 2: It's a question related to Sweden, only!
