That's correct, I'm a dual citizen living in the UK. I'm glad to hear we don't have to hand over our GTF list when we 'land'. Due to work commitments we need to come back to the UK as well as settle our affairs / sell our house, so I'm extremely glad we can wait till our stuff is packed and ready to be shipped out later next year to give them our list.
I guess I just got a bit confused because
every 'landing thread' seems to imply you have to have these forms ready there and then
Many thanks to steaky for clearing this up for me (and qorax for confirmation)
