Both my parents born & bred in the rebel county (Cork to those who didnt know), came over here in 60's as many others, to work....I was born here. Had UK passport but a few years ago, went for irish one too. The irish embassy in London were quite twattish about it all....had to supply all my details, including my (now defunct) marriage cert, birth cert...AND my folks wedding and both their own (now tattered) birth certs before they would consider me.
What got my old lady narked was that they give passports out to asylum seekers over there who aint even a hint irish and she told the pen pushers that as well. Got it in the end though. No problems with it at all, apart from once visiting america, one dozy immigration clerk typed in IR in to my arrival data log on his pc instead of IE for the country code. Carried on my journey to Vegas no problem. Only on my departure 2 weeks later flying out of Vegas the check in girl said i had been booked in as an Iranian so I would need to join the other long long queue of "alien" nationals..got searched 4 separate times...almost missed my flight......i mean she agreed i didnt look iranian but what could she do ? I said "look, my middle name is Patrick for God's sake !!" No difference. Luckily i was spared the rubber glove search.
All because some minimum wage desk clerk couldnt be bothered to look up the country code for Ireland.
Rant over !
