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.
What is a Visa? The main difference between a visa and a passport is that a visa is an endorsement placed within a passport that grants the holder official permission to enter, leave or stay in a country for a specified time period. The most common visa types are tourist, student, work and transit visas.
