same here, but my visa is a carpenter visa instead of engineer. Been working for almost 3 years and so far nothing bad has happened - visa wise. The only thing is that it is hard to get a family visa for my family. That is so far the benefit I cannot enjoy due to my visa status. Otherwise, everything is ok. If you're single then, i don't think there will be a problem unless you are not being paid as agreed. Anyway, you can try to ask your company to change it to an engineer visa, i have tried to ask them each year, but still they're not working on it. so i guess it depends on your mandoob....
