Ria
Ummm, that's somewhat arguable. The southern tip of Ireland is at 51.5 degrees north, which is either in the "northern latitudes" or pretty close to the edge. I wouldn't call it "mid-latitude". Let me put it another way; the southern tip of Ireland is well north of the northern tip of Maine, and about on the same latitude as Labrador, Canada.

The Euro is the currency of the Irish Republic! The Republic of Ireland is what some people mistakenly call "Southern Ireland", so the answer to your question is yes.
The Republic of Ireland is often used, but the official name is Éire in the Irish language and Ireland in English. Southern Ireland is an incorrect term. In fact the most northerly point on the island of Ireland, is not in Northern Ireland, but actually in what many people call southern Ireland. So "Southern Ireland" is an incorrect term both as an official name and geographically.
It is called Ireland. Its official name is Éire, which is what you will see on Irish coins, stamps and official documents. It is often referred to as the Republic of Ireland. To distinguish it from Northern Ireland it is often incorrectly referred to as Southern Ireland which is neither politically or geographically accurate. The most northern point on the island of Ireland is actually in what people call Southern Ireland and not in Northern Ireland. Nicknames include the Emerald Isle and the Land of Saints and Scholars.
An immigrant is someone coming from a country other than the one that they are now in, usually with a requirement for documentation, like a visa, to enable them access to the country they are now in. In the context of Ireland, someone from the Republic of Ireland (the proper term for what people call southern Ireland) living in Northern Ireland, would not be considered an immigrant. Someone from the Republic of Ireland going to some other countries could be regarded as an immigrant. It depends on where they are going.
