We would also appreciate an explanation as to how far a 'sponsor' (possibly parents) could help meet this requirement. Is there any statistic showing people with sponsors being more/less likely to get approved?
To clarify, every fiance/spousal visa MUST have a sponsor.
There is only one person who is allowed to be the sponsor and that is you (the UK citizen fiance/spouse).
It used to be that 'third party financial support' (i.e. from parents) was allowed for a fiance/spousal visa, but since the rules changed in July 2012 and the new financial requirement was introduced, the third party support allowance was stopped.
Secondly to note, my fiancee tried to visit me in the UK without a visa last October and was unfortunately turned away at border control and sent back to the US. Will this have any major impact on our application?
It won't prevent her from getting a fiance or spousal visa, but it will mean that she will need a visa to enter the UK from now on (even if she's just visiting) and also that all future visa applications will take longer to process as they have to look into the reason for the refused entry.
Also, it means that for future visa applications made in the UK, she will not be able to apply in person, she will have to apply by post, because only straightforward applications can be processed same-day at an in-person appointment.
But this all only affects the time it takes to get the visa, not the chance of the visa being granted.
Thirdly, is it worth getting an immigration lawyer to look over our application before sending? Does anyone recommend a specific lawyer who helped them?
If the only complication is one refused entry, then it's probably not worth using a lawyer. There's lots of information on the UKBA website about how to apply, and plenty of help here at UK-Y, so you shouldn't need to pay for a lawyer to help you.
Does staying with parents lessen the chance of visa approval or no?
It makes absolutely no difference.
For meeting the accommodation requirement, if you are staying with parents you would need the following documentation:
- a letter from your parents giving you and your fiance permission to live in the home and stating that it won't be overcrowded with you both there
- their land registry document or deed
- their most recent mortgage statements, if they have a mortgage
