Needs to visit US if you’re from Ireland. It would be better if you simply petitioned her for lawful permanent residency. She could come visit and go as she liked without always the fear it would be denied or she would be turned back to Ireland. The Consulate Processing Petition would have to be prepared.

This pathway is referred to as consular processing.
