I have a kiwi passport and a UK one. Obviously because of brexit I can’t stay more than 180 days in a year… however could I do 90 days in one schengen country on my uk passport, fly to another schengen country, get stamped, on my nz one and then do that kind of on a loop in order to stay in Europe for 360 days out of a year and then just do 5 days outside of Europe or in the uk for example?
Tbh I believe the ‘legal’ answer is ‘you are only one dude, having multiple books with your face in them don’t make you two people’
This being said… reality isn’t always this straight forward.
Imo you’ll be fine, and if not… what’s the worst that can happen? You get sent back?
Neither of your passport have the chip? That’s weird are they very old?
