Hi, I have a potential employer who is willing to support me for in getting a work visa. The thing is I dont have a culinary qualification, and I work for them for almost 8 months. The question is, am I eligible to get to a work visa? and what particular visa should I apply for?

I finished a Diploma in Hotel Management Course (lvl 7, New Zealand). And at the moment I am on a Post- Study Work Visa Open.
