HI DUDE,

FIRST OF ALL HEARTIEST CONGRATULATIONS FOR THE BABY GIRL. MAY GOD KEEP HER IN PEACE.
I THINK YOU HAVE TO GET THE VISA AS IT IS MANDATORY AND SHE HAS TO GET THE EXIT STAMP ON AIRPORT WHILE EXITING QATAR. AND THAT IS NOT POSSIBLE WITHOUT VISA.

THE PROCESS IS NOT DIFFICULT AND YOU JUST NEED TO SUBMIT THE MOTHER PASSPORT AND BIRTH CERTIFICATE ALONGWITH THE BABY PASSPORT AND IMMIGRATION PEOPLE WILL GRANT THE VISA.
HOPE THAT WILL HELP.

THANKS
