Thanks! Covered all the bases there I think...just WOW.
Yeah... it was a saga.
Thing is, if he had returned to the US to apply instead of doing it from inside the UK, depending on her benefits, they might have been able to qualify under the 5-year path based on being exempt from the financial requirement. In the end though, it was a 2-year battle from inside the UK, multiple applications, various lawyers and I assume 10 years on expensive visas.
He could have potentially been able to get ILR and UK citizenship by 2020, but I guess it's going to be at least 2026 now.
