Hi all!
I'm new in this forum!はじめまして！

I'm Italian and I have been living in Tokyo since 2002.
I worked in the fashion industry for the past 4 years under the Specialist in Humanities/ International Services Visa.
Due several private issues, last autumn, I quit my job.
Now I'm ready to go but tired of office life, instead than looking for a new boring job, I decided to prepare myself to enter in a university next April and be a student again (and hopefully once graduated to work in the music industry).
In that while, I'll have to eat somehow, so I have no choice but to do some part-time job.
What kind of part-time job am I able to do with my current visa, besides Italian teacher or English teacher for kids?
My visa expires on April 2014.
Also, once I'll be a student again should I "downgrade" to College visa or I can just study under the current visa until expiration?

Any kind of help and advice is highly appreciated!
Thanks in advance!!!

Alex

p.s. I googled a lot for this kind of info but didn't find anything yet...
