I think you may have a problem with her travelling on her own, or with anyone except you her mother...more-so because she is a female minor.
My wife had gone on ahead to England before our family moved back there from the Phils.
She had to come back just to accompany my (then 13 year-old) step-daughter, who already had a ILR for UK, and had previously been living there for 4 years.
I would advise you to consult the DFA in the Phils and get clear advice on this.
