Hi Scott!!...yes she can attend CFO Seminar while her visa is still on process.
After I submitted all my documents with the VFS for a spouse visa I went straight to CFO Manila and attended a one on one interview with CFO Officer and they gave me a certificate, they just ask a photocopy of my marriage certificate and my passport and tell me that once my visa is out and approved I need to get another certificate and a CFO sticker to be attach in my passport before I leave the Philippines.
