Darn these people who use 'txt messaging' on the WWW! ;D
What's CDO? - 'Can't Do Ought'!?!
Make sure you marry in the UK, and bring her here on a Fiancee visa, any other way will cause problems with the immigration in future.
Their is a link for the form on the main page, download two and fill one in yourself for practice, then take them with you, and have the future missus fill in the real one, and go with her to the British Embassy.
She will be given an interview about a week later, so go with her. You can't sit in with the interview, but they usually want a word with you afterwards. (It helps your case). Also take all letters, copies of emials, mobile txting bill, to prove your long relationship. Always take MORE than they ask, it impresses them, and works in your favour.
Once she is in the UK, you have to marry in the first 6 months. Inform the Immigration of this, and the Philippine Embassy, as she will have to complete & pay for a Philippine marriage certificate.
