I have two passports where one of them is not OK with with dual citizenship. As suggested by previous questions posed that I should fly to a neutral country - "C" which does not need visa as transit and then fly into the single citizenship country -"B" -entering using B passport.
However on my return to A (dual citizenship) country via the neutral country using my A passport, would it not be strange not to have an B country exit stamp on the A passport especially you just flew out from B country? (As you enter and leave your (single citizenship) B country using its own passport) Would the neutral country's immigration question this and report to your B country?
