“.....However the two did get to Kenya where a marriage did take place which was nullified at a later date in Hawaii by court and public records.....”
Except Kenya did not allow bigamy, so o SR could not convey UK citizenship to 0.
Since SADO was too young, she could not convey US citizenship to 0 (in the US eyes, she was married, and since O SR didn’t apply for residency, the ins didn’t pursue the bigamy investigation ).
Are you sure that Kenya did not allow bigamy either as was the situation in Hawaii?
