Samrachu,Any person while exiting while he is on visit visa requires exit permit from the sponsor,I also got wrong answers from peoples that it is not required,But when my brother was exiting qatar while on visit visa last week he was been asked by immigration,and at the last moment there was a night mare for me to arrange exit permit in such a short time of 2 hours,You can go to departure of airport,Opposite of car park there is a small building of white colours which issues exit permit,but sponsor only has to apply for it.I hope you got the answer.
