Does anyone know how long it takes to post overseas? They use DHL right? Just worried I won’t be in when it gets here as I’ll be away from 15-20 July.
Also did not need an interview for a first UK passport (never had one before – only a USA one). Pretty happy this only took 2 months given the circumstances – good luck everyone!
