I'm from the U.S. - and my boyfriend is from Ireland. Over the past year and a half, each of us has been traveling back and forth between the U.S. and Ireland under the visa waiver program. He has been here to visit me in the states four times to date, and I have been there twice (but am planning to go again in about a month) I know that, technically, under the visa waiver program, I am allowed to go to Ireland as often as I'd like, as long as I go home every 90 days for some amount of time - but I have also heard that there is a possibility I will be turned away if I try to go too often.
Does anybody have any experiences in this matter - or is able to give advice?
