to the filipino/uk forum, Jason ... and enjoy your forthcoming visit to the Philippines.
Simply utilise the links provided by the others who have already responded to your introductory post. It's understandable the idea of bringing the lady in question to the UK for a follow-up visit will have crossed your mind. And what could be more logical? (you'd think!) But the main stumbling block seems to be the British Government's inherent suspicion that overseas visitors from non-European countries will be tempted to stay on indefinitely once they're here. Which, of course, has the knock-on effect of resulting in many [bona fide] 'Tourist Visa' applications being denied.
So it makes sense for a potential visitor to prepare him/herself well beforehand by ... for example ... supplying an employer's letter clearly stating that he/she will have a job to go back to on his/her return.
