Multi exit permits are only given to Pilots and upper Management types. Cabin Crew and other employees are not allowed and will not be issued Multi Exit permits. all others will only receive single use exit permits.
the ability to have multi exit permits are given to very few companies in Qatar.
keep in mind when given a multi exit permit the company reserves the right to suspend the privilege.. meaning, if your a bad boy the company will and can block or suspend your exit permit, Thus you will not be able to leave the country.
