Disclaimer: This question is only theoretical to me, but could be reality for other people I guess. I will write the question AS IF I would be the person wanting to travel in those conditions.
So, I "am" the citizen of two countries. People from these countries must have a prior visa in their passports before traveling to the other country.
But since I am a citizen of both countries, I should not need a visa at all, just to use the proper passport in the proper place, right?
Well, I have this idea in my mind that in the airports (and maybe other places) I might encounter some issues. Since the ticket is round-trip, and since the tickets are linked to one of the passports, how can I travel without trouble?
Ideally, I do not want to show both passports, and I do not want to buy two independent tickets, each linked to one of the passports.
