For parents over sixty, visit visas for 6months are issued only after the approval from Captain. It dose take a couple of visits to his office at main immigration office, first floor building no. 1. I recently got my mother’s visa approved after a couple of visits to his office, first time he told me the visas are closed and asked me to comeback after a month I returned to his office after 2 weeks with the same application which he rejected and got approval on the same piece of paper.
