Can I use a different nationality/passport when visiting country again?
I have dual nationality; let's say country A and country B. I am traveling to a third country, country X. I have previously used passport A to visit country X. On my next visit I want to use passport B to enter country X instead. Will this be a problem?
Countries B and X are both in the European Union, but country A is not. I want to work in country X, so using passport B is much better than passport A, since I don't need a work visa. The reason I used passport A previously is that I did not have a valid passport B at the time (I have never actually lived in country B).
I want this to be a general question, but to be specific X=United Kingdom, B=Germany, and A=United States. There are other questions on this site that deal with traveling between A and B in my situation, but I am visiting a third country and am worried about being inconsistent with my passport use.
Best Answer
Unless you're a citizen of one of the countries (in which case you're often, but not always, required to use that country's passport to enter/exit that country), there are no problems using a different passport.
Germany does not record entries and exits, so they have no idea what passport you previously entered on.
So yes, you can use your German passport in the UK without problems. In fact, you won't even have to see an officer, as you can use automated face recognition gares as a German citizen.
Lastly, as pointed out by Calchas, a German cannot be refused entry to the UK other than on serious secuity grounds. They do not require any permission to enter, or even live, in the UK.
