What visa did your wife arrive under? I'm guessing FLR(M) since you are now looking to go for ILR.

Your wife had to pass an English test to the acceptable standard before coming to the UK in June 2012? We understand that this pass is acceptable for ILR and you don't need to re-take the test even if it 'expires'.

Also, if she arrived under FLR(M) then she will now be on a Spouse Visa with a 2 year validity. Our understanding is that you cannot apply for ILR until 28 days before your current Spouse visa expires, not 28 days before her 2 year arrival anniversary?

Terpe, where are you?
