Hi. I had obtained residence visa for my family (wife and 2 children) in April 2012. They stayed here for a month and returned to India. The plan was for them to keep returning every six months. But due to some health and education issues they could not travel. Now they have been out of Qatar for about 21 months. When I applied for a return visa it was rejected. Is there any means or solution to obtain a return visa without having to cancel their current residency and restart the entire visa process? My elder son will be 18 in March and their visa expires in April. Please advise.
