I'm sorry to hear that u're leaving. I would suggest b4 u resign there u must get a job offer in ur country so by the time u get back ur income flow should not start.

I wish u best of luck!! if possible for u to sacrifice a little on accommodation i mean instead of living in a big villa if u can manage to live in a 2 room flat i would suggest u not to leave right now. Qatar is good place and u try to manage ur sponsorship to some other co.
