I am currently enrolled at a Japanese university in the doctoral program of Mathematical and Life sciences, and have already been a student for last 4 years. I am waiting for the acceptance of research paper, and based on it, will submit the thesis for defense soon.
But I came to know that Japanese universities have a system where one can actually quit the university, but if the paper has been accepted, one can apply within one year for a thesis defense. A PhD degree will be awarded in the case of successful defense.
My question is, has anybody here been such a situation, and is aware of a possible difference between the technicalities of the difference in PhD degree, while remaining a university student, and after quitting the university? I know the concerned university or department should be the best place to answer it, but just in case anybody here can clarify that, I would be grateful for it.
At the minimum, will the degree obtained after quitting the university, would it be considered equivalent to the degree obtained while as a student or not? I guess other country universities don't have such a system in place. Thank you very much.
