If I have a job that sponsors my working visa, can I work a part-time job without any changes to my visa?
If yes, do i need to ask my employer for permission? Or do I just need to get that 28 hour stamp on my id card like students can get?
If no, what would I need to do to be allowed?
Any links / sources for claims would be helpful. I searched the webs without success. 🙁
EDIT: if it matters, it would be a job at a Japanese university. 助手、助教、講師, something like that. The part time job would be unrelated to teaching.
