might be a good idea to do that asap, get her to contact any companies, nhs,docs, gov, bank to change from her old address to your address, and register her with other companies at your address and collect as much evidence of this as possible from now til her visa expires.
you might be able to apply for a Unmarried Partners Visa for her, but you need 2yrs evidence of living together, you've got less than 2yrs thou, but might be possible to apply for a visa here to keep her here for a bit longer (student), or if you could go and live with her in the phils for a month or so ?? to get 2yrs worth of evidence.
