Do my years abroad count?

My state pension record says I can top up the 10 years I was abroad, however, I am doubting I am truly eligible. I am an American who moved from the US to the UK in September 2003 to accompany my husband who was on a student visa. I did work during the 3 years we were in the UK and got some NI credits from that. In June 2006, we relocated to Canada where we lived for 10 years. I am assuming I am not eligible to claim any NI credits from my time in Canada both because I was not a UK citizen at that time, and had not lived/worked in the UK for a solid 3 years before we left. Is this accurate?

Hi Erin Ortlund,
You can find the criteria for paying Voluntary Contributions abroad by reading NI38 on the gov.uk website.
You’ll then have to apply using the form CF83 Application to pay National Insurance Contributions abroad.
This can be completed online or by print and post.
Once we receive your application our caseworkers will be able to investigate your circumstances to see if you are eligible for making payments. 
Thank you.
