mine is actually a first adult passport as someone born in England, never having held one before.
Yup interview for you – it’s been policy for a few years. While mine wasn’t technically a first passport as my actual first passport was issued back in the 1980’s and long lost and they no longer have records of those passports I had to apply as if it was my first – I too was born here. Mine was done online and it’s really nothing to worry about – unless of course you’re trying to steal someone’s identity!!
