Is 8K your total, all-inclusive salary? Single or Married/Dependents will also be in Qatar? Your status and standard of living impacts your salary. Assuming 8K is total salary, if Single you will spend at least 5K/month for housing (sharing accommodation only), transport, food, etc. If Married w/ dependents (non-schooling), you will be lucky if you are left with 1K at month end.
