DR, Is your Son Above 18yrs if not, then he does not need a Exit Permit, but If He is above 18yrs then Yes Its better to get a Multiple Exit Permit, Fill out the Exit Permit Application Form at http://www.moi.gov.qa/PermitForm/PermitFormE.jsp, Take out the Print & Visit Airport Immigration, & it takes hardly 2 mins to issue a Multiple Exit Permit...

Happy Vacations!
