I am a UK citizen with Green Card (resident alien status) who has worked in the US for 20 years in local government. My wife is a US citizen. Eventually we would like to return to the UK and I realize this may cause my US status to change to non-resident alien. Will I be eligible to claim US social security at 66 while living in the UK? Thank you.

Hi,

Yes, assuming that you have at least 40 quarters of U.S. Social Security coverage . The U.S. has a totalization agreement with the U.K. which permits citizens of the U.K. to receive their U.S. Social Security benefits while they are living outside of the U.S. (https://www.ssa.gov/pubs/EN-05-10137.pdf).

Best, Jerry
