Just wanted to know. If we approach a bushiban, how can we be sure they are legal, and are in the position to sponsor our ARC and National health etc. Aside from asking them directly “how many years have you been in business” is there like a government agency or regulatory body which you can contact who can tell you if the school is legal or not? I read in this forum that usually at the front reception wall they will have a certificate hanging up that testifies to them being a legal business entity. But assuming that not all bushibans follow this practice, how else can we be sure?
