The Common Travel Agreement between Ireland and the UK has been in place since 1923, allowing citizens of both countries to travel freely between each other without the need for a passport or visa. However, with recent changes in both the UK and the EU, there has been some confusion among travelers regarding their rights and obligations when traveling between the two countries.

Firstly, it is important to note that the Common Travel Agreement remains in effect and British citizens are still able to travel to Ireland without a passport. However, as of October 2021, those traveling from the UK to Ireland must have a valid form of identification, such as a driving license, to be able to enter the country. This is due to Ireland introducing new immigration rules as part of its preparation for the post-Brexit landscape.

Similarly, Irish citizens traveling to the UK will no longer be able to use their passport as a form of identification when entering the country. They will now need to apply for an Electronic Travel Authorization (ETA) before traveling which can be done online. This new requirement was introduced in October 2021 as part of the UK`s new immigration rules following Brexit.

It is also worth noting that while the Common Travel Agreement allows for free movement between Ireland and the UK, this does not extend to travel throughout the rest of the EU. British citizens may still need a visa to travel to some EU countries, and Irish citizens may face similar restrictions when traveling outside the EU.

Furthermore, the Common Travel Agreement does not guarantee the right to work or settle in either country. Citizens of one country may need to obtain a work permit or visa if they wish to work or reside in the other country for an extended period.

In conclusion, while the Common Travel Agreement between Ireland and the UK remains in effect, there have been recent changes to immigration requirements that travelers should be aware of. It is important to have a valid form of identification and, for Irish citizens traveling to the UK, to obtain an ETA beforehand. As always, those traveling for work or to stay long-term should seek the necessary permits and visas.
