my daughter will be 15 when her passport comes up for renewal in March next year. will she only be able to renew it for 5 years again or are we better waiting until she has turned 16 in April and she can renew it for 10 years?

Also at the moment her passport is machine readable, (issued March 2003) will she need to get a visa to travel to USA in 2008 or will her new passport cover her? We live in Scotland so I don't know how easy it is to get a visa up here!

Thanks

Elaine
