Hi, I can tell you that you will have to go through passport control at Dublin's airport and my passport has always been checked. However on returning from Dublin to the UK I have never had to produce any I'D at Heathrow T1.
As the "Common Travel Area" is in place, you do not need a passport to go to Dublin from the UK. When flying between the UK and Ireland it is best to ask your airline what form of ID will be accepted.
Yes
No, a South African citizen does not need a visa to visit Dublin or anywhere else in Ireland. If you are travelling via the UK (even in transit) I think that you now need a visa. (Not for Ireland but for the UK.) Worth checking out prior to travel just to be sure!
Yes you would need a passport. You would also need a visa.
Only Irish and UK citizens can travel without a passport between the 2 countries
not if you are an Irish or UK citizen. Other nationalities may be asked to produce passports/id cards
that depends totally on your nationality. The only people who do not need passports/visas to make this journey are Irish or UK citizens
If you are a British or Irish citizen you can travel anywhere in the Common Travel Area (UK, Republic of Ireland, Isle of Man and Channel Islands) without a passport. Airlines require photo ID, however.
A passport is not needed to travel between the UK and Ireland.
Dublin in Ireland is not part of the UK, but there is a Dublin in Suffolk in England.
Two and half to three hours from London based airports to Warsaw.
Yes, Colombians need a visa to travel to the UK.
