Good Morning - I am a uk citizen and I lived in france for five yrs before brexit arriving In 2014 i left france and went straight to ireland where i still reside so i have been here for 12 yrs - my question is - if i returned to france which i am considering would i have to go through all the hoopala as if i lived out of the euro union and coming from the UK or as i have not left the euro union would i still be considered a resident of the euro union and can travel freely [ so to speak] without going through all the new regulations which came into its own after brexit - If I still would be considered a resident of the euro then how would i go about getting residency in france when i returned > thank you for your responses and have a good day
Unless you have an Irish passport then yes, you are now a third country citizen and would need ro apply for a visa to stay in France for more than 90 days.
@JaneJones summed it up perfectly - unfortunately “EU citizenship” was never an actual thing (a court case was brought by UK folks opposed to Brexit to try and establish it, but the European Court ruled that citizenship applies on a nation-state basis only).
Citizens of EU member states have freedom of movement within the EU, but your UK passport is the thing that counts not your Irish residency, and since the UK is no longer an EU state you would need to apply for a visa along with the rest of us British plebs. 
Welcome to SF.
I don’t suppose there is any chance of marrying an EU citizen - that would greatly simplify movement to another EU country like France?! Alternatively if you don’t currently have an Irish passport are you able to acquire Irish citizenship, perhaps given your length of time spent in Ireland?
thank you for your reply however i think marrying a eu citizen just to move into the country or reside their freely is a bit drastic 
I don’t know, I got married for a house. A rental house at that 
now i am giggling ….
I would (obviously!) never suggest doing something as cavalier as that. What I had in mind is knowing a number of long established couples (where one was an EU citizen) who got married to smooth their move either to France, or either EU countries.
thank you george your explanation is wonderful..
I think you can do that if you have been resident in Ireland for 5 years out of the last 9:
so if that was possible …would i be a dual citizen or have to throw away my UK passport…?
You can have an Irish and UK passport.
You should definitely apply for citizenship after all those years of residing in Ireland. I managed to get Irish citizenship for my husband a couple of years ago and, compared with some countries,the process was pretty straightforward. And his situation was complicated.
thank you Helen much appreciated to all..I will look into it
I have looked into it and heres the result: I dont want to wait up to nine yrs for a decision - PATH 2: Citizenship by Naturalization
When learning how to become a citizen of Ireland by residency (or naturalization), you must be able to demonstrate “reckonable residence” for at least 5 of the past 9 years. This includes a year of continuous residence in Ireland in the year leading up to your application (with an exception of 70 days granted). The qualifications for what counts as “reckonable residence” can be complicated, so be sure to check the stamp(s) you are/have been on. You must also be able to demonstrate “good character.” People married to Irish citizens have a shorter residency requirement (more below), along with people granted refugee status. You must also intend to remain in Ireland.
Becoming an Irish citizen through naturalization requires specific documentation. The necessary documentation includes proof of identity, and proof of residence for each year counting for your application. This is required prior to getting an Irish passport.
Pros: All you need is flexibility, time and an understanding of Irish laws to gain naturalization status.
Cons: It is very lengthy process taking about 5-9 years, of legally working and living in Ireland under a visa to gain citizenship.
anyway…i think i would rather jump through all the hoopla’s to live in France as a uk citizen.subject rather then get irish citizenship - but thanks to all responses
It’s not that complicated! As long as you can show minimum income and health cover it’s pretty straightforward.
That quote is misleading - the “5-9 years” is not the time it takes to get citizenship after applying, it’s the total time including the period of residency.
Google says this:
Processing Period: Once your application and required documents (like the 150-point residency proof) are successfully submitted, processing by Immigration Service Delivery (ISD) typically takes 12 to 19 months.
So yes not super-quick but you have already been resident for an extended period so as long as you have been resident in Ireland continuously for the past 12 months you should be able to apply now.
thanks chris…i am thinking of selling up in Ireland right now [ i dont want to wait] as the housing market is for the sellers there is a shortage of smallholdings in ireland at the moment and they are getting good prices - the medical system here is abominable and has a shortage of drs and nurses - in fact ireland has got a shortage of everything including laws to prevent the invasion of its borders ireland has changed drastically since i arrived back in 2014 - but now …..
and also i read that if you apply for irish citizenship they will require that you live here…..hahahahahaha - thats the trick
