Proof of social integration for Belgian nationality
I would like to apply for Belgian nationality and I saw that as proof of social integration one can submit a diploma obtained in Belgium. I have obtained PhD diploma here but I am not sure if I can use it. As I saw, on some websites it's written that the courses should be in one of the national languages. However, in Belgium, there are no courses during PhD. So, I am really confused if I can use it or not. Any ideas?
