I am surprised because Sheen Services is known around the city for providing proper guidance to many. Since they are in this business for quite some time, I may be wrong in my earlier comment. However, I would suggest you take the views of others especially people of your country who may be more knowledgeable than me about the rules in Qatar on such matters..
Meanwhile, I will see if I can get more information on your query either to correct my information or to stand right.
