Welcome.
it would be wise to visit your girl in her homeland in the first instance. That's what I did myself ... twice in fact ... after corresponding with a *Filipina lady [now my wife!] for almost 12 months.
My first visit took place a year past September ... during which time, we were virtually inseparable. It was then I realised that *this was the woman I wished to spend the rest of my life with, and we began making plans for our future together.
After a stay of thee weeks, I came home in order to obtain what's called a Certificate of No Impediment from my local Registrar's Office, whilst she made arrangements to procure its Philippine equivalent, known as a Cenomar. Each of these documents is in effect, a statement confirming that the parties concerned are free to marry. In OUR case this procedure was relatively straightforward, since both of us had been widowed.
In late November 2008, I made my second trip to Davao del Norte Province in Mindanao, then flew to Manila to present my CNI at the British Embassy in exchange for the Phils 'Legal Capacity to Marry' version.
The wedding took place on December 8 ... following which, I stayed on until mid-February to await the result of my wife's spousal visa application that had been submitted on January 20. Finally, she was able to join me in the UK on March 8.
I hope your relationship has the same happy outcome.
