I am reading it that is starts on the 28th, So if you scheduled before the 28th then you are good.
I don't understand why they would put such a burden on an applicant, We scheduled my wife mother for a Tourist Visa Interview last week, for the September 25th, we beat the deadline if we would try to schedule after the 28th then she would of had to fly to Manila just for biometric and a picture, and then fly back to home and back to Manila for her interview.
I dont' get it, this seems very stupid to me.
