Please could somebody tell me the best (legal) way to go about getting married whilst I am in America and attending the Mayo Clinic for treatment. My GF is an American citizen and we would like to get married after the treatment is finished. It is expected to take 3 or 4 weeks. I have had one previous course of treatment this year and am now currently back in the UK whilst my GF is at her home in America. We want to get married and live in America, but we would both like to be able to travel back to the UK and Europe whenever we want. If it makes any difference, we are both 70 years old and pensioners.
