Gharrafa Immigration is the Place where my friend was able to convert Tourist Visa to a Family Visa..
The captains name was Mr. Nasser Al Attiyah...
May be the captain has changed... Check there...

Also I had been to Onaiza Services Centre..there also a very good captain is there. In Onaiza there isnt much rush...But the rush at Gharrafa is a very difficult one.
