Short layover in Dublin- making the connecting flight

I don't think you will have a problem. If I remember correctly if your landing in Ireland and it's not your final distination you won't have to go through imagration. It's not the same visa for Ireland as it is for the UK.

You'll make the connection easily.

There is no customs or immigration control between the RoI an the UK.

What visa?

Coming fromUS you don't need a Visa.

Ireland and the U.K. are part of a Common Travel Area. You normally go through immigration when you first enter the Common Travel Area so I would expect that you would go through immigration when you arrive in Dublin from the U.S. However, the other posters seem to think there is no passport control. I have not been through Dublin in 10 years so perhaps they have changed the rules.

Sorry I used the word "Visa" - I'm talking about the custom's entry stamp that activities your 90 Visitor Visa if your in Ireland or your 6 month Visitor Visa if your in the UK.

When flying into the Republic of Ireland (this only applies if the Republic of Ireland is your final destination) you receive a 90 day Visitor Visa Stamp (yes the USA is part of the visa waiver program with Europe, but you still have to have an enter stamp), true there are open boarder between the Republic of Ireland and Northern Ireland. But if you cross over the Irish Sea to Wales, Scotland or England you must show your passport (non-EU citizens) and get a new Visitor Visa Stamp for there i.e. the UK 6 month Visitor Visa Stamp and then the same goes for main land Europe.

Back to your question again, you won't have any problem getting your next flight.

Dublin airport is not set up for airside transfers in any circumstances so everyone connecting there has yo go through immigration.

There will be no further immigrstion formalities arriving in London, presuming you are a non-visa national. This does mean you only get the shorter stay period, not 6 months you would I general be granted if entering the UK directly.

Marco - it would seem we are both right, I did a connection flight but from T1 and I was in the 200s gate so I didn't go through immigration. But if your flying into T2 (cause it's new and they didn't build a tunnel connecting) you do have to go through, I don't really understand how that works with the Irish entry stamp towards the UK entry stamp (I think it's must be like how it is in the States). But here's the website.

You can't guarantee to have flights landing and departing in the Gate 200 area though, and the effect is unintentional.

Incidentally this is why if you do need to activate a UK visa, say as a student, you must not enter the UK via Ireland.

Marco
When flying between the Republic of Ireland and the UK you do go through passport control and get a stamp (non-EU members) when you land. It really only becomes complicated if your flying out of Northern Ireland into the rest of the UK, they don't check.

' customs entry stamp'
No such thing, immigration stamps passports, customs approves goods.

' if you cross over the Irish Sea to Wales, Scotland or England you must show your passport .....'
Nope, you have to show ID. Whatever falls out of you wallet first is fine.

If you want the official statement, look at paragraph 15 of the immigration rules.

If it were possible to just pass through the Republic of Ireland then immigration would need to be gone through in the UK. However, since the intention at least in Dublin Airport is for everyone to go through immigration this does not arise.

The land border between the Republic of Ireland and the UK is completely unmarked anyway.

Thank you everyone! It sounds like 1.5 hours will be enough time to connect in Dublin coming from USA going to London.

I believe I will be flying into terminal 2 in Dublin- the Aer Lingus website says all flights from USA fly into terminal 2, and all UK flights go through terminal 2 as well.

Thank you again!

You got caught up in numerous discussions so am glad you decided to not worry about connection time. Good luck.
