I forgot to mention that the show money required is QAR 5000...it should be either in cash or in bank. If it is not in cash, your brother must have an atm card...as he will be asked to prove that he really has the amount required...he will be asked to go to atm machine to print the bank account balance amount. But this is not also a requirement at the immigration in Philippines...this is just required at the airline's check-in counter.
