I am a permanent resident and divorced.

I need to know if i relinquish my green card and move to Ireland, will I be able to collect Social Security on my former spouse earnings at 65? I don’t have enough of my own.

Hi. I assume that you're an Irish citizen, which is pertinent because the U.S. Social Security program has a totalization agreement with Ireland. In that case, then yes, you can be paid any type of U.S. Social Security benefits that you qualify for even if you move to Ireland. The requirements for divorced spousal benefits are outlined in the following section of Social Security's handbook: https://www.ssa.gov/OP_Home/handbook/handbook.03/handbook-0311.html.

Best, Jerry
