I am 18 and I still have a childs passport which is still valid for another 2 years. Can I travel with this passport or do I need to apply for an adult one?
If your child is under 16 they cannot apply for an adult passport. For example, a 15-year-old who needs a passport must apply for a 5-year child passport. They can use this until it runs out, in this case when the �child� is 20.
When a child reaches 16 the next passport they apply for once their current 5-year child passport runs out should be a 10-year renewal adult passport.
