Sorry, I shouldn't have said lied, but my concern was just that if she did all those things on a visitor visa should she get some extra help when applying for the visa?
I know that you can get married in CofE, and as I said almost all family visas are granted, but if you enter as a visitor and then do things once you arrive that visitors wouldn't do, such as get permanant housing can this be an issue?
It can be hard to prove intent after the fact is all.
If she gave up everything to move here then she shouldn't have been moving over on a visitor visa. Even if the IO didn't ask specifically about settlement, it would have been a lie of omission and my main concern would be if they might consider this deception.
Most family visas get approved, but does careful wording need to be used in application letter?
Also, did she register with, or use, the NHS? That would be another concern.
