Goludumdum, did you even read 'Karen Andrews' story. She says her husband took loans from bank. He was in debt and resigned. Thereafter, he tried to leave the country and was caught (I presume at the airport) and jailed. Obviously he will be deported since he resigned, and in gulf the company cancels the visa after an expat resigns and leaves the country. When his visa is cancelled won't he be deported after serving jail.
I can understand if you are not aware about the 'jail laws'.
