Retiring in the UK

Yes, I can confirm we do pay into social security each month.

I forgot to mention previously that I also have a 7 year old son who was born here and has UK citizenship. Not sure if that makes a difference.

Not for your taxes. 

Or for the visa.

Or for the visa.

LOL...yes, that's the angle I was going for.

You could, if you can prove it would be unreasonable to expect your UK/US citizen child to live in the US.  Not sure how easy that will be as the US is not war ravaged and has medical and eduction available. Plus that route to ILR  is really expensive and now has much stricter rules. 10 years to ILR; which is 4 lots of visas to apply and pay for and be granted and 10 years of Immigration Health Surcharge to pay. When people accidently find themselves on this route, they often opt to return to their own country and apply for a spouse visa instead; a 5 year route to ILR.
