hi...before you leave Doha be sure that you have the NOC which u will give to the new company that will going to hire you its either here or in philippines....coz once you left, and your previous sponsor had already cancelled you, you cannot enter anymore here. and they (new sponsor) cannot apply a new visa under their sponsorship if there's no NOC...Best thing you have to do, get an NOC first, wait for the new sponsor to trnsfer the visa for them and then go exit in philippines and at anytime you can go back here as long as the visa transfered and issued under new sponsorship.
