Changing from student visa to tourist visa

Hi I'm studying in a language school and have just graduated. I wanted to change my visa from student to tourist because my school said I have 2 weeks to leave the country/they will cancel my visa because I have graduated.

I called the immigration office and they said I just need to go down to their office and go through and interview and they can change my visa(I'm from Singapore btw)

I went down today and the people from the student section said it is not possible. I called the immigration office again and another person told me to just go down to their office. When I told him what happened he changed his answer.

Has anyone had any experience with this before?

I want to stay because my girlfriend is working here and I'm about to enter university in another country so we wont be able to see each other anymore

While I don't have any experience with this, as far as I know, immigration bureau is the official source of information, and is the one who can do anything about your student resident status. Your school cannot cancel it; all they can do is to inform immigration that you�fve completed your course.
