Hi,
It all depends on how much is your income? and how much you save,as a expat you will never get a green card or citizen ship here in Qatar or any GCC ,So think,calculate,plan,save,its your game,it will be difficult for you to adjust here in Qatar, if you are coming from Dubai,you will not get that standard of life here,very limited sources of entertainment,very few shopping malls,limited school,limited hotels and restaurants,house rents very high.
some ideas for you from UAE returned friend ,
happy living
bye
