hi everyone!

We are planning to apply for a visa for our mum (wifey's mum). We've read on ukba site that we need to provide the ff:
letter from the sponsor
letter from the visa applicant
evidence(s) that she will return to phils
evidence of her properties
What else do we need to provide for her visa application? do i have to give them my bank statements since they haven't mentioned it on the site? does she need to take the english test? any advice will be much appreciated. thanks!!
