Welcome to the forum James.

You seem to be going about things the right way so far.

Probably cheaper (and nicer for your fiancee) to marry in the Phils.

Personally I think it shows more commitment as far as visa application is concerned too.

Also your new wife will be able to work straight away in the UK, should she wish so to do (instead of being bored witless at home).

Just make sure you hang on to that steady job plus your home here in the UK, and start maintaining a bank account in the black.

Oh, and also keep a record of your communications with each other, dated photos of your times together in the Phils, with the family etc.
