Is it possible for a dual national who happens to be a citizen of two countries to travel between two countries who can accept only national IDs upon entry from their own nationals, and hence not require stamps to their passports (either because they're not stamped by their own authorities either because they're not necessary)?

Let's say I'm a citizen of Belgium and the UAE, and both countries require only national ID(s) from their respective citizens to enter. Can I simply switch between national IDs, in a proper manner of course?

    But I'm talking about using 2 national IDs for countries that allow entry with them – user102129 Sep 4 at 13:05

    That may depend on the airline as some do not understand ID cards or require passports for other reasons. – Willeke Sep 4 at 13:10
  • @name, the fact that the link is here twice is because of how the site works. When people vote to close as a question is identical (or very closely related) to an other question, the link to that question is posted as a new comment. Most of us understand that you do not think it identical. – Willeke Sep 4 at 15:05
  • I am refusing to be the fifth close vote because this is a different question. – Harper - Reinstate Monica Sep 4 at 18:04

In general this should be possible.

Some countries might have restrictions on the use of ID cards. For example, the US passport card is for use as a travel document only for land and sea travel to Canada, Mexico, or the Caribbean. Such a country might not permit its citizens to use the ID card when arriving from certain countries.

But most countries recognize an obligation to admit their own citizens, so the adverse consequences of violating such a restriction, if any, probably won't include denial of entry.

One must also convince the airline to allow travel with the card. Airlines use a database called TIMATIC to check these requirements. TIMATIC notes that both Belgian and UAE citizens can enter with an ID card, so in this case it should be possible.

The US seems to have a somewhat problematic and poorly documented requirement that departing passengers be in possession of a passport. Any country that has such a requirement might pose a problem to such a traveler, but I recall reading a report here about a European who managed to fly to Europe from the US with her ID card, after some discussion with the airline's ground staff.

As an aside, a Belgian can also avoid stamps from EU and Schengen countries by presenting the Belgian passport.

  • Yes I had verified with Timatic before asking this very question. I also know that there are countries do not allow It, so I asked about a specific scenario in specific conditions. – user102129 Sep 4 at 13:55
  • Thanks for the answer. By the way regarding the case you have said has been reported, the airline should verify whether the document is valid for entering the country destination from anywhere, NOT for the country the traveler is in because the same thing can be raised about a permanent residence of a PR who has to go back in his PR country, because the PR card has no value in his country of origin, but the airline staff is forced to let him in because the document is valid for the destination. That's the same thing. – user102129 Sep 4 at 14:02
  • Even if there are particular cases that certain travelers can enjoy in, such as less restrictions than usually faced and using less papers than those required in normal scenarios, those travelers might find difficult to discuss and make the staff understand that they enjoy that particular privilege or right. This is insane sometimes, especially in the third world Arab country I'm from, if I show my EU national ID at check-in and tell them that Europe allows entry with only the ID, they'll question it and make me use my passport instead, even if I can do the former. – user102129 Sep 4 at 14:16
  • @name the airline is required to follow the laws of all countries in which it operates. If a country has a law requiring departing travelers to have a passport and airlines to verify this, then the airline has to comply. A permanent resident in your example generally has two documents, the other one being the document that he or she used to enter the country of departure. In most cases this will also be necessary to clear the departure country's exit controls. – phoog Sep 4 at 14:18
  • Of course it has to verify, but what I was meaning is it has not the right to be stricter than the country of destination's laws in terms of documentation upon entry. If a simple national Id is enough, than they do not have the right to require a passport just because it is the general norm for the rest of the nationals. – user102129 Sep 4 at 14:37
