The relationship between the UK and Ireland when it comes to visa policies can be a complex and nuanced topic.

While the two countries share a close geographic and historical connection, their visa requirements for travelers can differ in important ways.

One of the key things to understand is that the UK and Ireland operate separate visa systems.

A UK visa, whether it's a visitor visa, work visa, or any other type, does not automatically grant access to Ireland.

Likewise, an Irish visa does not necessarily mean you can enter the UK.

That said, the UK and Ireland do have a special arrangement known as the Common Travel Area (CTA). - https://irelandfocusguide.com/blog/does-uk-visa-include-ireland/?unique_id_gj1bsxz7
