Sorry, "minimum" is a typo. Yes it's a maximum of 20 hours a week, and if I understood correctly, you can do 20+ hours full time work a week during vacations.

Anyway, my job right now is different from what I want to take. I am working with printers but I want to become a chef. So I thought the opportunity is enticing. God-willing, I wish to be trained in the kitchens of Heston Blumenthal, Marco Pierre White, or (snicker) Gordon Ramsay. Maybe not, but despite the stereotype of British food, fine dining in London is the most renowned in the planet, along with Paris and New York (actually Paris is number one).

My concern though is do I have to report to POEA if I were on a student visa even if I were a working student?
