I still have my EU (UK) passport, and intend to continue using it to bypass the hideous immigration lines when arriving at London Heathrow. Outside of the EU, I'll be traveling on my US passport.
Huracan thank you for being more interesting! Your pithy insights bring a fresh breath into this stuffy forum. Still a public forum right? Still allowed to ask boring questions right? Don't need to comment on everything - smart ass!
You're lucky, dude. I guess you'd use whichever passport would be more advantageous in any given situation, eh? Are you never going to live in the EU again?
And, I agree that most people wouldn't want to give up other citizenships, but sometimes, there're things like military service to consider. Some people would love to give up Singaporean or Israeli citizenship, for example, in order to avoid the service.
Boatyard? Fascinating. What do you do?
Service manager, marine electrician, occasional diesel mechanic, general dogsbody.... I do most everything if the situation requires it.
Way less stressful than when I worked with telecom software development.
