I was working out of UK prior to 2014, immigrated to the UK in 2014 and has been in full time employment in UK since then. I have now completed 10 full years of national insurance contributions and that has made me eligible for minimum state pension whenever I reach state pension age. As, to be eligible for full state pension 35 full years of national insurance contributions are required, I would need 25 years of additional contributions from hereon. Given my current age, I will fall short of that even if I work upto the retirement age. So, I was wondering if it would be possible to buy national insurance credits for the period prior to 2014 (When I worked out of the UK) to be eligible for full state pension. Please guide.
