as an accountant you should know better that you cannot compare salaries in different countries like for like :o)
You need to look at what your Qatar salary buys you in Qatar... and it buys you nothing. With QR2,400 here you will have to share a room in a 'cheap area'. You will literally live on 'survival level' and won't be able to do much... plus - you're away from your family. You need to ask yourself why you are looking to come here, honestly.
