She must go back to the Philippines and file annulment. When its all done get marry again but this time in the Phils and apply a fresh application.

I think this is her only option and I knew someone who did the same before.

Just hope that your wife's first husband wont file anything against her...Bigamist! (I think).

This must be done asap and also seek an advice from the solicitor or go to Citizen Advice Bureau.

Goodluck!
