As background, I'm a dual UK/US citizen living permanently in the UK. Read this in the context that I know nothing about US Social Security and little about the UK State Pension.
I recently received an US SS statement with a "Your Earnings Record" that shows taxed SS earnings and Medicare earnings for the years 1976-1979; i.e. for summer jobs that I held during university in the US. Afterwards, I've only been employed in the UK and hence my SS earning record shows zero for the years 1980 to now. The statement also says "To get retirement benefits, you need 40 credits of work. Your record shows you have at least 11 credits at this time, including assumed credits for last year and this year if you continue to work."
For the UK, my national insurance record shows that I have 27 years of full contributions (towards my state pension), 7 years to contribute before my state pension begins in 2023, and 2 years when I did not contribute enough.
Dumb questions:
1) Am I correct in assuming that I have established no entitlement to receive any US SS payments when I retire?
2) Can the 11 credits for US SS somehow be transferred to qualify for incomplete years of my UK State Pension?
