If she will go visit visa way under your sponsorship, she wont make it still as both of you didnt meet eachother yet. Another thing is, majority here submit chat logs etc worth atleast 6 months that proves that you are keeping in touch with eachother and obviously you cant provide it since you only met her a month ago.
Like Rayna said and the rest, keep the communication going for the meantime and maybe after a year come down and visit her and her family in the Philippines.
That is the best you can do, you will have the chance to see the culture, the place, understand the family ties and bond and enjoy the beauty of the country.
Most important thing is be wise, use ur heart in balance with ur brain and refrain from sending any money to any that you have just met online. It doesnt mean that pictures and things you ask her to do she will do and she is then genuine. You will only know if a persons genuine in time, slow process but tested and proven.
