First, you cannot cancel your sponsor’s visa! what a nonsense. HE is your sponsor, not the other way around! And he is the one who can cancel yours… Second, don’t think you are so smarter than qatari government.. WHY do you want to come on Visit visa? To look for the job, right? And then – what? If you found the job, you will need an RP, right? and you won’t get it without NOC.. but anyway, even to come on Visit Visa you will need a NOC, otherwise the visa won’t be issued…
