I am a U.S. citizen, and have just received word today that my Green Card Permit has been approved, so we're ready to move to Ireland (Co. Westmeath). We're planning on staying very long-term, and I'd foresee us applying for Irish Citizenship after our first two years.
BUT
I have two daughters - one is 16, one is 19. The 19 year old isn't currently going to school/college/university, but she'd like to.
I know my 16 year old can come along, since she's a minor, but there's no WAY we'll just leave our 19 year old here in the States. Does anyone have suggestions on what options we may have to bring her with us?
My original thought was we could have her come over for 3 months, then come back the States for a couple of weeks to visit Grandma, then back to Ireland to stay with us for another 3 months. But I just read somewhere that she has to be out of Ireland for 3 months before she can come back for 3 more months. Is that true? That won't work for us!

We could enroll her in college, but she'd definitely want to stay close to us and live with us. I suppose she could overstay her 3 months (visitors visa)?

I'm pretty desperate, as I LOVE the job I've been offered and really don't want to pass it up, and we LOVE Ireland - and have been there several times. I'd sure appreciate any feedback. If you have some suggestions you'd prefer to keep quiet, please feel free to send me a private message.
Thanks so much!
