An official passport is a passport which is issued to someone who must travel internationally on official state business. These passports are issued specifically to people who need to travel, rather than to people who are being assigned or posted overseas.
The regular passport is often referred to as a tourist passport although it is also used by those who travel for business, study, work and other purposes. A regular passport book has a blue cover and is issued with the standard 28 pages or non-standard 52 pages. This type of passport has a validity of 10 years when issued to an applicant age 16 or older and 5 years when issued to a minor age 15 or younger.
