I also have a similar problem. I also have an active visit visa in qatar. It was issued last month. The problem is i haven't used the visa and now i am being hired in qatar. My employer cannot process my working visa since i have an existing visit visa. How long does it take for my visit visa to expire.. and if ever can i just send a letter to the embassy to cancel my previous visa? Is there any other way to cancel my visit visa exept for just using it and have an exit? TIA;-)
