The CFO seminar is normally done when she received her visa. But whilst waiting for the decision from ECO she can attend the CFO seminar (SMEF-COW and once the passport arrives with visa stamped in it then she can get CFO sticker.
OR
wait when she's granted with visa.. then attend the seminar to get the certificate and have the passport stamped with CFO sticker at the same day. Your gf needs to be at the CFO centre very early.. around 7am. And it will depend which centre since they have different schedules for different countries.
CFO seminar and sticker is required for filipinos who leaves the Philippines for good.
