Title says it all.

I have a pretty new US passport and a brand new UK one. Do people keep the old ones? It has the corner cut so wondering if it can go in the trash or if I need it for some of the old stamps (eg when I applied to have conditions removed on my GC).... Why am I worried? Trump is why.

Cheers!

Doesn’t hurt to keep it. Are you or any family member interested in family history or genealogy? I have passports (not all, but several,) of my grandparents and my mother, as early as 1930. Of course, back then they had more good stuff in them - visas with stamps stuck in etc. In the 1960s, my parents and my passports have the handwritten record on the back page of foreign currency withdrawn from the bank, as you could only take a very limited amount.

Unless you obtained your US citizenship via fraudulent means then I don’t see why you would be scared of Trump. I would probably keep the old UK one if not living in the UK and go back to visit and it should act as proof that at one time you were a UK citizen and probably still are but there again you already have a valid new shiny UK passport.

Yes I expect the "well some US citizens have been detained by ICE etc etc" but given the huge numbers of dual citizens living in the US and have travelled with no incidents why would you be worried.

You are in a very very small percentile which is probably is less than the small boat arrivals in the UK.

Unless you want to keep them for sentimental or other reasons then the choice is yours. Some will say keep them some will say bin them.

Trumps assault on the country and it's citizens (naturalized included) should be heeded, if not actionable (yet).

It is a fair question, and yes, of course I am here legally.

Yes, I think that’s fair. We all need to keep a weather eye on the US government, and be prepared for unwelcome changes.

Expired UK passport is likely not going to be sufficient, with the new Electronic Travel Authorization process coming into effect, if you are a UK citizen then a current UK passport will be needed.

obviously not an issue for the person asking the question as they have a new one!

Actually, you just need proof of UK citizenship. I entered in October on an Australian passport, with just a photo on my phone of my UK passport. An expired UK passport would definitely fit the bill. At present they are not insisting on UK citizens travelling on UK passports - though that may come in time!

I wasn't suggesting anyone attempts to travel on an expired passport rather carrying the expired UK passport along with the valid US passport if travelling to the UK. The expired UK passport could be shown if questioned and the officer has doubts about a verbal claim of UK citizenship. It appears now that a number of countries are now insisting that if you have duel citizenship then carry 2 valid passports. If living in the US then using the US one if leaving and entering the USA and UK one to enter the UK.

Good to know, thanks for sharing. Right now, from my experience, the airline has not been checking for an ETA when only showing US passport at checkin (to go to the UK), but if that does start to happen, they might insist on a UK citizen having a valid/current UK passport. Fun times with all these changes!

Seems like February 2026 will be the go live date for ETAs being required and therefore UK Citizens must get UK Passports to fly to the UK https://www.gov.uk/dual-citizenship

Worth keeping.just additional proof of citizenship or visa approvals, Any actual stamps in the passport may have value- some of stamps in older passports have values , and there are some collectors of passports. I had a work visa for one country , and years later applying fro another I showed my older one and helped smooth the newer visa. One never knows with changes whether old passport may be helpful.

I’ve got all my old passports, UK and US. Sentimental value for sure.

Keep for sentimental value, and sometimes because you might have an old visa in it that you will need. For example, when I apply for a new visa to visit China, they ask the number of my last Chinese visa, which might be in an old passport. Stuff like that.

It's probably due to PTSD from US Immigration - but I keep a high quality scan of all visas and passports I have had electronically just in case.

I've kep all my old passports.
