"On August 1, 2023, Pi Alpha Phi National Fraternity announced the closure of all undergraduate chapters."
"While some current students may still be attending school, Pi Alpha Phi does not recognize, endorse, nor support operations of these groups. Students at these schools are not allowed to join these organizations and should take note that should they choose to join, they will NOT be recognized as members of Pi Alpha Phi and may also open themselves up to sanctions from their local university."
