go home while you still can. theres no point in keeping your hopes of landing a decent paying job by staying and renewing your business visa. employers here will take advantage of the fact that you are just on visit visa and offer you much less than what you were expecting before you came here. obviously your friends misled you into thinking that finding a job here is easy. sure there are lots of jobs available, but most of the companies who have the means of paying a decent salary recruit outside Qatar. you would have better chances of getting a decent paying job if you applied back in Manila.

don't fret. its not too late.
