Once this new law comes into being then I couldn’t use my US passport to get into the UK as the place of birth in my US passport says England.
Boris wrote a piece in The Telegraph back in 2006 about his denial of entry and his subsequent renunciation of his US citizenship. He had no idea at that time how difficult it is to give up US citizenship and it took a full 10 years before he had caught up with his back taxes and finally relinquished his US citizenship in 2016.

Big new topic for dual citizens, which includes myself (UK and Australian).
Some context first:
I cannot find any information about what happens if you are in the UK under a different country's passport, on the date the regulations change!
Does any one know? Cheers.
Some context first:
- I emigrated from UK to Oz 15 years ago, and become Australian Citizen about 10 years ago
- I held UK and Australian passports until my UK one expired 5 years ago, and I didn't renew
- I have travelled to the UK a number of times to visit family/friends in the last 5 years (short holiday visits only) and used my Australian passport to get in and out of the UK
- I am travelling back to UK again and land on 20-Feb-2026, i.e. 5 days before the new regulations come into force
- I will be leaving the UK on 4-Mar-2026, i.e. after the new regulations have come into force

You might choose to renew your UK passport while you're there, if its easier for you.

Well f$#@.
So even though I and my 2 minor children (one born in England, the other born in the US and British by descent) have US passports, we're ALL going to need UK passports when we come over in June?
I thought there used to be major issues with using a US passport to leave the US (as required by law) and then a UK one when you land as it confused the airline's manifests? Is that not the case anymore?
This just sounds like a huge money grab by the UK passport office... 🤔

Leave US with US passport and on arrival in UK show UK passport. Flight manifests nothing to do with being examined by an officer or using a kiosk.
Depart UK on US passport and show US passport on arrival in US. It’s that simple if you hold 2 valid passports.
Under the new regulations if you are a dual citizen of ANY country you will now need a UK passport to enter the UK.
Dual citizens cannot apply for the ETA on their foreign passport. Countries like Canada do not require you to leave on a Canadian passport but must use it on arrival back in Canada.

Husband who was a Canadian and US citizen did not have a valid Canadian passport two years ago when we flew to Canada. He entered on his US passport and left on his US passport. No one said a thing. So did the law change recently?

A lot of countries are now starting to implement the 2 passport rule if you have dual citizenship and resident/living in the other country as your primary citizenship even if VISITING your old country of citizenship.
Some will call it a cash grab others will say it is being done to improve security and me just calling it a PITA as I only want to go back to visit so I need a valid UK passport even though I have other documents to prove my UK citizenship.

I also tend to think for Trans Border (US to Canada vice versa) the officers are more relaxed as US citizens don't need a Canadian ETA so they dont care about this type of dual citizenship and Canadians exempt from ESTA's.

Guess he was super lucky as we flew into Montreal for his sister's memorial service and burial. No one questioned him. He just never bothered to renew his Canadian passport and by the time he needed it to fly, he would not have gotten it in time for his sister's burial. Now I just hope they don't need his passport for his ashes to be brought into Canada to be buried with his son in Nova Scotia this summer.

Now even if an officer found out during the examination I suspect they would not do anything apart from a bollocking if not carrying a passport as once on Canadian soil then he has a right of entry once established he is also a Canadian citizen. Canadian birth certificate is a good indicator or an expired Canadian passport in his possession and not being used at the kiosk or presented to an officer unless in the secondary examination area when pulled aside away from the primary examination area.

Importation of Cremated Human Remains Into Canada
10. Cremated human remains, because they do not pose a quarantine risk, do not require a death certificate. However, it is recommended that when transporting the cremated remains that the importer should carry a copy of the death and cremation certificate and ensure that the remains are in a container that can easily be scanned (e.g., cardboard, wood or plastic).https://www.cbsa-asfc.gc.ca/publicat...eng.html#s03_2
I would take a copy just in case and why you might ask well it's not like drugs have never been smuggled in disguised as Ashes
I took my dads back to the UK in 2023 had all the paperwork and hand carried and no problems whatsoever.

As far as USA, the American consulate in London states "By law U.S. citizens must enter and depart the United States using U.S. passports, even if they hold a passport from another country."
So I always wondered if one checked in on American passport in USA, but then enter UK with British passports, why it would not be flagged an American citizen got on the plane but then arrived but o record entering UK but your comment about the manifests explains it.

I always find in amazing that flight manifests are not automatically forwarded to the UK to check on who is coming into the country.

I suspect the US are similar in how they do stuff but hey we are dealing with humans and mistakes are made.
At least the Southern Border is a bit more secure now and I will say no more less I offend others

Is this the type of information you get access to as part of retirement? What else do you know? I’m looking forward to retirement even more now…

Retiree Former Lancastrian has been advised that this must not happen again. As you suggest, there is a wealth of esoteric knowledge that is vouchsafed to people when they attain Retired Status - and not before. Beyond that, my lips are sealed.
