Immigration Q&A: Is Irish citizenship possible for my second wife?
You say that you and your wife would like to spend an extended amount of time in Ireland after retirement, but the new naturalization requirements may well be more than you bargained for. But certainly, it will be possible for both of you to visit and enjoy Ireland.
Americans do not need visas to enter Ireland. They can be granted stays of up to three months at a time.
If you’re looking to remain longer, it’s possible for the spouse of an Irish citizen to obtain a visa for long-term residence. For information, visit the Irish government’s Naturalization and Immigration Service website at http://www.inis.gov.ie/en/INIS/Pages/WP09000003.
