If someone goes on holiday in 12 weeks time is now time enough to apply for a first time passport bearing in mind they interview now? if it doesnt arrive in time there will be tears :(
Worth using the Post office facility for taking the photos (they have to be exactly right) and checking the application, then they send it off for you - there's a fee but at least you know it'll be 100% correct when the PO send it off.
Errr Boxy - if you read experiences about the Post Office "service", you'll find that it is error strewn and offers no guarantee of anything - or indeed compensation (or even return of fee) if they cock it up - which they all too often do.
Get a local passport photographer to take the pictures and have the form checked by a couple of literate/sensible friends.
