You can work in any field, parttime, fulltime, other than IT.
I'm also working in the IT field, but if the need arises, I will be working as a mechanic (they earn almost the same as IT does) in either automobiles or motorcycles. And this is one of the things I really love doing, so I'm not really scared of losing my job now because of my gc.
These times call for everyone to be well-rounded in jobs as the IT industry is on a down-turn.
