On the passport declaration form it states: 'For dual nationals a full colour copy of any uncancelled non-British or British Overseas Territories Citizen passport relating to you'. I interpreted this as we would need to provide a US Passport copy since she is a dual national, even though we have not even got her one yet, but it seems that you don't think we would need to? I just don't want to send off her application and then get a jobsworth at the UK Passport office who kicks back our application because of this, extending our wait time even longer.

I have heard from a friend who has a family member who works in UK Immigration who has said that there is a lull in passport applications this time of year (post Summer) so I would likely get it back well before Christmas if the above were the case, which is beyond good news to me right now. Just wanted to share that information in case anyone is in a similar situation.

It didn't seem to cause a problem and I wasn't asked for it or about it. I received my new British passport back the week after I sent in my application.

Just one datapoint.
