Un update.
Just had a call from my friend's wife, Arlene. She is in MNL, and has passed through controls and is now waiting at the boarding gate for her flight on way to Spain.
I believe she had the 'normal' for Schengen Area, 90 day tourist visa, which will allow her to apply for permanent resident status in Spain and a single ticket to Spain. The same as the wife of my ‘friend’ from Madrid had, when she was stopped in Cebu and made to buy a return ticket.
I will up date this info, when Arlene has arrived here in Spain, for the benefit of anyone in a similar situation.
