That's all I can say about the Embassy's decision to charge €1.90 (approx. $2.38) per minute to call for Visa information.
It is much cheaper to call the INS in the US at 00-1-800-375-5283. You'll have to wait on hold (undoubtedly) for a while, but if you call after 6pm Dublin time, it should still be a lot less than calling the Embassy here. Don't tell them you're calling from Ireland, tell them you're calling about a brother/sister/whatever who's in Ireland and wants to visit. They won't know the difference.
UPDATE 10:00am: Of course, whether it's cheaper to call the INS in the US depends on your phone service. I'm not sure what the Eircom rates are these days, but I'm paying 6 cents per minute to call the US using Vartec.
