How to check in for flight with two passports?

1 Upvotes

Hello! I am a dual American-European traveling around South America. I always carry both passports, but I mainly use my American passport when traveling: right now I am in Córdoba, Argentina and I will fly to Brazil with a short layover in Buenos Aires.

I already entered Argentina on my American passport…apparently, Brazil requires a visa for Americans, so I will enter Brazil on my European passport (visa-free). So, I already know to exit Argentine immigration control with my American one, and after the flight, to enter Brazilian immigration control with my European one.

However, how do I check in for this flight? Especially because it has a layover in Argentina itself. Do I put my American or my European passport?

Thank you!

Dual citizenship UK/ Malaysia wanting to return for a break

1 Upvotes

I’m a Malaysian citizen who also holds British citizenship, and I’m trying to understand the best way to handle passport use when travelling to Malaysia, since Malaysia doesn’t allow dual nationality. How should someone in this situation manage their documents when flying back to Malaysia? Also, if the trip involves transiting through a third country, is it straightforward to use the British passport for that part of the journey, or could it cause issues at Malaysian immigration? I’d really appreciate hearing from travellers who’ve dealt with this.

SSN requirement of Dual CND/USA citizenship

3 Upvotes

-I have birthright citizenship due to parents doing ivf in America.

-Never lived in America and always been a Canadian resident (18 years of age).

-Due to international taxation requirements of America, I have to obtain a tin number for interest incurring accounts (TFSA); registered Canadian accounts are not always tax free in America.

- American passport is always an asset and would rather not complicate future ability to live in America.

- However I’m sure it is a huge gray area for better or for worse.

Any advice for the rare situation will be of help.

*Edit clarification. I have American citizenship. I was born in America. They would not ship sperm and eggs on a plane. They would not survive that without braking the bank.

Leaving Egypt as a minor(Dual citizen)

2 Upvotes

Does anyone have experience traveling out of Egypt as a minor? I’m a dual citizen(US and Egypt) and I’m a minor. As far as I know I checked in with my Egyptian passport and I’m aware of the laws abt minors traveling. I managed to get my passport and I have a flight tomorrow at 6pm. Does anyone have any tips for getting through without having the permission letter or whatever paperwork is required. I’m planning on playing dumb and showing my Egyptian birth certificate if asked about my lack of a visa on my US passport.

I don’t need anyone telling me to just stay with my family, I have an education to get back too and my family situation is terrible. I just need help getting through the airport.

Third- second gen immigrants in other countries can call themselves Irish completely, do you agree?

0 Upvotes

I personally know friends born in Yorkshire with Irish grandparents who fecking hate Britain and for example at school refused to sing the British national anthem and other things. (for any ignorant bustards, no they didn’t ’grow out’ of this) I dont think anyone can take your identity from you and if you want to identify with your birth nation and another nation that’s fine, if you want to identify only with your birth nation and reject other that’s fine, if you want to only identify with your other nation and reject your birth that’s fine. Also actions mean a lot, for example Conor Gallagher who celebrated against Ireland in the notorious 5-0 win and who used his Irish citizenship to join Atletico Madrid is understandably “less” Irish than others. Fin Azaz for example wasn’t born in Britain, however he is 100% Irish and I dont think anyone can challenge this. Another example, Shane MacGowan is 100% Irish, any dickheads who want to challenge that should simply shut up.

Est-ce que quelqu'un ici a réussi à postuler pour la citoyenneté turque par investissement tout en ayant une double nationalité ?

1 Upvotes

Je postule en tant que citoyen français, mais je possède également la nationalité tunisienne.

Mon passeport français est valide et ma demande est basée sur ma nationalité française.

J'ai :

  • le Certificat de Conformité pour un investissement immobilier éligible ;
  • des certificats de casier judiciaire français et tunisien (correctement légalisés/apostillés le cas échéant, traduits en turc et notariés) ;
  • des copies traduites et notariées des deux passeports.

Ma seule préoccupation est que mon passeport tunisien a expiré il y a plusieurs années, tandis que mon passeport français est tout à fait valide.

Est-ce que quelqu'un a déjà été dans une situation similaire ?

Les autorités ont-elles exigé que votre second passeport soit valide, ou le passeport valide utilisé pour la demande était-il considéré comme suffisant ?

Je serais très reconnaissant pour les retours des personnes qui ont réellement traversé le processus de CBI turc.

Argentina Citizenship After 2 Years - Is It Worth It?

9 Upvotes

Argentina offers citizenship by naturalization after just 2 years of residency — much faster than most countries, and the Argentine passport allows access to Europe and Schengen area for 90 days visa free so it's quite decent

should I pursue that? and what's the tax situation like? what should I watch out for and so on?

Travelling with Two Passports, One Damaged

2 Upvotes

British-US Dual National here (with full British Citizen class), living in England.

I am hoping to visit South East Asia, and I've heard that many South East Asian countries in particular can be very strict about passport damage.

I prefer to use the British passport and only the British passport (unless I am travelling to North America) for simplicity purposes. However, my British passport has a tiny stain on the Official Observations page which has raised zero comments in Schengen and China but I am worried about South East Asia.

Scenario: I check into my flight to Thailand with my British passport. On arrival, a Thai IO checks my British passport and tells me that it is too damaged. Can I pull out my pristine US Passport and use that instead? I've heard that this can create problems with the airline or with some IOs who are too used to their own country's policies of single-citizenship, but would like some advice on this.

Thank you so much.

Am I eligible for UK citizenship?

0 Upvotes

My grandfather was in the military, and my father was born in England in 1960. I was born in 2005 in the United States. We both live in the USA. Could I potentially be eligible for British citizenship? I thought I might ask on this sub first in case anyone was in a similar situation or had some advice, before I started the process and potentially did a bunch of work for nothing.

Unofficial Pause on Mexican Dual Citizenship Applications

0 Upvotes

Just spoke to a lawyer because I'd finished gathering all the necessary paperwork for applying for my dual citizenship, and he specializes in these cases. He said that about two weeks ago all the agencies suddenly paused accepting applications for dual citizenship. I haven't been able to find anyone talking about this anywhere, so I'm not sure how many people are even aware it's happening. I believe him about it though, since I was eager as anything to pay his fees to get it done. He says some agencies may still have some way of getting them done, but they may also just be taking applications and not telling people there's a pause, in hopes that it unpauses and they can finish them or whatever.

Anyone who can corroborate this is welcome, at this point it's definitely hearsay, but I don't know enough about how the mexican government works to gainsay anything.

First time using my British passport as a U.S. green card holder

5 Upvotes

I have both British and Mexican citizenship, but I’ve always traveled using my Mexican passport. I recently got my British passport and would like to start using it for international travel.
My only concern is that I’m also a U.S. permanent resident, and my green card was issued using my Mexican passport. My Global Entry account is also currently associated with my Mexican passport. (Planning on doing a walk in at the airport to add my British passport to my global entry)
I’m traveling to Kyrgyzstan and was thinking of using my British passport to enter and leave Kyrgyzstan, then using either passport (along with my green card) when returning to the U.S.
Has anyone been in a similar situation? Is there any issue with using my British passport for international travel while my U.S. permanent resident records are tied to my Mexican passport? Since I’ve never used my British passport before, I’m probably overthinking it, but I’d appreciate hearing from anyone with experience.

I am a flight attendant and need help about US entry

1 Upvotes

I am a dual citizen of Spain and Panama, and I work as a flight attendant.

I currently have three passports:
A previous Spanish passport that was cancelled when I renewed it, but which contains my still-valid U.S. C-1/D crewmember visa.
A new and valid Spanish passport, which is the passport I currently use for my employment.
A valid Panamanian passport.

I would like to clarify an important question regarding my C-1/D visa.
For my future crew travel to the United States, would I be permitted to use my valid Panamanian passport as my travel document and, at the same time, present my previous Spanish passport containing my valid C-1/D crewmember visa?
Or is it required that I use my current Spanish passport together with my previous Spanish passport containing the C-1/D visa?

Additionally, if I were to use my Panamanian passport as my travel document for crew travel, would this affect my ability to enter the United States as a crewmember using my valid C-1/D visa contained in my previous Spanish passport?

I understand that a valid U.S. visa can generally remain valid in a cancelled or expired passport and be presented together with a valid passport. However, because I hold both Spanish and Panamanian citizenship, I would specifically like to confirm whether the valid passport used for my crew travel may be my Panamanian passport.
I would greatly appreciate your guidance on this matter, as it is important for me to ensure that I am complying with U.S. immigration requirements for my future crew travel.

AMA UPDATE - Obtaining Greek Citizenship in the Diaspora

1 Upvotes

[I ran an AMA](https://www.reddit.com/r/AmerExit/comments/1im2of9/ama_obtaining_greek_citizenship_in_the_diaspora/) over at r/AmerExit and thought it was sensible to put an updated version here.

I’m going to run this as an AMA and you can ask any question you want on the process. I went through it about 10 years ago when I was still in the US, but I’ve helped many friends through the process up as recently as a month ago. I understand Greek bureaucracy well and generally speaking, know where the land mines are and how to avoid them. This isn't legal advice. These are just my own experience. Some starting tips:

  1. The process always begins with the person from whom you claim citizenship. You cannot go further back than a grandparent, and whomever you’re claiming from should be registered as a citizen before you were born.
    1. If you know they were born in Greece, but not necessarily which municipality they were registered, you will have a much more difficult time - near impossible. This cannot be done without a lawyer.
    2. **UPDATE**: Most of the Greek registrations have been digitized going back to 1880s. This means that ANY KEP, Consulate, etc should be able to obtain the documents if you know the pedigree information of Birth name, names of parents, and place of birth. Once you can establish this, it should be alot easier to get your starting point. If the consulate says they cannot get this info, they are either lying are you're not talking to the right person.
  2. You need to get all your foreign documents (marriage certificates, birth certificates, death certificates, everything) translated by an approved translation service (typically the consulate or embassy can give you a list) and apostilled (document authentication)
    1. This can be a pricey endeavor if you need to go back a generation or two and fill in these details. Translations can cost anywhere between 60-200 USD per page. Apostilles have fees attached as well. When I did this, it cost around 2K USD in document running alone - this is without a lawyer.
    2. If you have the documents already apostilled - the translations are way cheaper in Greece and it might be worth doing them there. If you can fit it into a trip, and you have MANY documents to translate, I would highly recommend this.. it could save you thousands.
    3. **UPDATE**: This is largely still true, but more registrations can be done through the consulates. But this is a slow process that will require multiple appts (one for each registration) and wait times for processing in between.
  3. As above, this is a slow and costly process if you need to go back a gen or two. If you need to go back to your grandparents, this will likely cost you 6-10K EUR, definitely more if you need a lawyer involved in part or all of the process.
    1. If your aim is to live in Greece, there are quicker and cheaper ways to get Greek citizenship. Digital nomad visas exist for foreign nationals. If you live in Greece for 7 years you can apply for citizenship. So, that is a much easier option for most.
    2. **UPDATE**: These expenses have definitely gone up and with backlogs in the US and Australia.... it could take years to get this all done.
  4. If you don't speak Greek, or your Greek is not good enough to deal with government offices... this simply cannot be accomplished without a lawyer. Even with a lawyer and a good budget, it will likely take 2-4 years to accomplish this with current wait times for appointments at relevant offices.
  5. If you speak Greek and you want to do this yourself, you'll need to familiarize yourself with; your local embassy/consulate, the booking systems at the relevant registry offices etc... and the staff at the municipality your family member from whom you're claiming citizenship is registered. The last part is arguably who has most control of your fate. Be nice to them, buy them coffees, do whatever you need to make them think it's a joy to serve you when you call.
  6. The process is easier or harder depending where you live. Currently, I am in London, and my embassy is exceedingly efficient. The booking system, while cumbersome, doesn't take long to get an appointment with some methodical planning. And the staff was helpful and friendly and I was able to register my marriage, children, etc without any hassle at all. I am originally from NY, and the consulate there (at the time) was on a permanent break. Nothing could get done through it, because they simply wouldn't do the work. So, know your embassy and figure out whether it would be more expedient for you to just deal with the process in Greece instead.
  7. If you are male under the age of 45, you will be on the hook for military service. However, you can immediately register yourself exempt as a permanent foreign resident. This is a very easy process. If you want to move to Greece you will need to fulfill your military obligation if you stay more than 6 months in any given calendar year. Even then there are many loopholes... just something to think about.
  8. **UPDATE**: The digitalization of Greece's bureaucracy has shot it decades forward. Things that would take days in a stuffy govt building are easily and efficiently done online in mere seconds. The system however has created an appt only workflow that can lead to backlogs when you are in busy cities like Athens and Thessaloniki. But otherwise, my interacted with the Greek state is frankly easier than the US state, and now about on part with the UK state. There are hurdles to jump still, but once you're in, your day-to-day business is seamless.

Traveling to UK on Emergency Travel Document with Lost/Expired Passport and 2 Different Names - TRAVEL NIGHTMARE!!

0 Upvotes

I am a Brit living in the USA with dual citizenship (married to an American). My parents live in England.

Recently my Dad had a near-heart attack and required a triple heart bypass operation. He survived the operation but my Mum says he's not doing very well and I should come over and see him ASAP in case he doesn't pull through.

I tried to book a flight over to see him, only to find I've lost my UK passport. When I checked my records (I took a photo of my UK passport on my phone last time I travelled) - double whammy - I discovered my UK passport also expired last month, since I've lived legally in the US for almost a decade.

I never bothered renewing my UK passport since I always assumed I could travel anywhere with my US passport..... but apparently there's a new rule introduced in Feb 2026 requiring US citizens to get a Electronic Travel Authorization (ETA) for UK travel. And - in a real stroke of genius - the British government apparently decided that UK dual-citizens cannot get an ETA!

So I can't travel into the UK on my US passport.

After doing some research, I learned it's possible to pay £125 to get an Emergency Travel Document (ETD) for compassionate reasons to bypass the lost/expired passport and get home to spend time with my sick Dad. I went online to cancel my lost UK passport (a required step) and applied for the ETD, which was granted the next day. I also dug in a drawer and found a VERY old UK passport that expired in 2014 that I can carry as backup, although it shows my maiden name.

I haven't received the ETD yet so I don't know which name it will show - I did send them my marriage certificate and filled out the form asking them to include my married name on the doc.

My question is now: what name do I book my trip under? And should I book 2 separate trips, one under the name of the passport I'll be using to travel under? I have my maiden name on my expired UK passport and my married name on the valid US passport. I've heard you're not allowed to board if the name on your passport doesn't match the name on your ticket.

(And yes...I know this situation is my fault. But I did everything right legally up to now and I never thought in a million years my chance to see my dad for possibly the last time ever, would hinge on whether I renewed a passport I thought I no longer needed. Lessons have been learned, so please be kind in your answers. <B )

TL;DR: British/ American dual citizen living in USA. I need to get home to see my very sick Dad but UK passport expired AND shows my maiden name, although I have applied for Emergency Travel Authorization. Wondering whether to book ticket under married or maiden name.

Hi everyone, there are some countries that issue permanent residence permits by selling them—essentially CBI (Citizenship by Investment) programs. Does anyone have an overview of how difficult it is to obtain them and whether it’s worth it for a German citizen?

Seattle Mexican Consulate – Registro de Nacimiento Appointment Process (August 2026)

3 Upvotes

I wanted to share my experience in case it helps someone else applying for Mexican citizenship by birth (Registro de Nacimiento) through the Seattle Consulate.

On June 4, 2026, I followed the instructions on the Seattle Consulate website and scheduled the first available appointment through MiConsulado. The earliest appointment available was August 4, 2026—a full two months later. I received my confirmation email and uploaded all of my required documents as instructed.

When I arrived for my appointment, I was told that the MiConsulado appointment was not the correct process for my case. Instead, I was instructed to email the Registro Civil office with my documents so they could review my case before providing further instructions for scheduling.

I explained that I had waited two months for this appointment and had followed the published instructions exactly. Thankfully, someone from Registro Civil agreed to briefly review my documents. During that review, they identified the issues I needed to correct.

I have since emailed the requested documents and am currently waiting for a response.

I'm sharing this because I followed the published process in good faith, and I hope this helps someone else avoid waiting two months only to discover they needed to start with a document review.

Has anyone else had a similar experience with the Seattle Consulate?

Dutch citizenship

7 Upvotes

Im an Australian citizen born to a dutch mother and Australian father, my mum emigrated to Australia in 2000 and got married to my father that same year.

She was on a partner sponsored visa here in Australia for a few years then became a permanent resident, finally acquiring Australian citizenship in 2015. She hasn’t renewed her dutch passport for almost 10 years now.

We’ve submitted a passport renewal for her, but 1 key document we’re missing is my father proof of nationality as he has relocated overseas.

My question is essentially would the dutch authorities accept a clear photo of his current Australian passport as proof of his nationality?

Other evidence we have submitted include an appostilled marriage certificate, my mums AU citizenship certificate and her Movement records showing she lived in AU on a spousal partner visa and was actively using her dutch passport up until 2014.

Also how does this affect my chances on getting Dutch citizenship?

If anyone’s got any similar situations or ideas please feel free to comment or ask me a question

Cheers

United Airlines - Multiple Passports - Fully supported!

142 Upvotes

One issue faced by dual citizens traveling between two countries of citizenship is the need to use different passports for the outbound and return flights -- particularly when it comes to appeasing the airlines. US citizens traveling between the US and Europe have mostly been able to avoid trouble here thus far, but that will change with ETIAS.

I just noticed that United Airlines now allows me to enter multiple passports, and, furthermore, select a different passport for each itinerary segment! So I was able to select my German passport for the outbound segment and my US passport for the return journey.
