Balikbayan Stamp and attending school (6th grade)

[BB Family 299]

I am still researching what we can do on balikbayan stamps. But long story short, i am retiring from the military, during the middle of the school year. We would like to travel to the Philippines for 4-6 months while our retirement home is being built. I am tracking that we can live in the Philippines visa free with the balikbayan stamp. But my question is can the kids attend school while they are in country on a balikbayan stamp. 

And really, thinking about it as i wrote this, all but one of my kids are dual citizens, so I don't actually think that matters for them. Just the one child who does not have dual citizenship. So of the whole family, only he and I will have a balikbayan stamp. My wife and our other children are all dual citizens. The one child is from a prior marriage and i have 100% full legal/physical custody. I believe i got my answer on step children receiving balikbayan stamps in a prior post, so now we just need to know if he will be able to attend school on it, or if he will have to apply for a Special student permit or student visa. Thank you!

Additionally.. this may or may not complicate things. Not all the children have philippine passports. But all the dual citizens have their reports of birth. So not entirely sure how that works. Since were in a state that does not have access to a consulate and depends on Outreach programs, we wont have time to get Philippine passports for the kids that are missing them. Would they still be able to enter the philippines as filipinos or would they be required to just get a balikbayan stamp in their US passports. Thanks again .
