I dont think two people having 10,000 euros each is necessarily proof of self-sufficiency.
By the way, could these guys just stay for 90 days, fly to London, get a stamp for six months in the UK, then promptly fly to Belfast and train back into the Republic, stay for just under six months, go back to Britain via Belfast, then fly back to the Republic and get 90 more days?
That basically covers a year. It's Ireland, they can't be too uptight about having a couple of Americans around.
Actually, I'm American and back in 2004 I flew between London and Dublin without even having a passport. My passport was at the Russian embassy in London awaiting a visa. I got on a plane to Dublin using my U.S. driver's license as photo ID, or maybe they never even asked for photo ID. Then when the plane landed in Dublin, there was a passport checking line for foreign passports , but there was also a uniformed man pointing away from the passport line saying "British or Irish? British or Irish? Just walk right through." So I mumbled "Oirish" and walked through. Then later I just re-entered the UK via the train to Belfast.
So I don't know that these guys even need to deal with the hassle of getting proper immigration permission. They should just shuttle back and forth as needed between the Republic and the UK and in the unlikely event that it draws attention they should just pretend to be dumb Americans.
