Visa from Philippines to visit Greece?

So Im a Greek citizen and I have this friend in the Philippines who I would like to invite to spend a two week vacation in Greece... So we are applying her a visa at the embassy, Im sponsoring her and Ive prepared all required paperwork in Greece while she does the same in the Philippines. (She basically has to prove that she has a good job, which is has and has a good bank record to prove that she is has no financial difficulties) The only problem is that she files only 6000 Pesos a month salary in her income tax returns... Do you think that will be a problem? everything else is okay!
