downgrading expired visas implications

my student visa is literally expiring in a few days (long story) and Im so tired of requesting the same documents from my school again and again and again just bc the "purpose" of the documents have to be different (not to mention the registrar was sick of seeing my face just today when i collected an overdue document they OWED me)

can i let the visa expire and process the downgrading slowly?? i know there are late fees but i dont know if there are other implications with it

my school will not help me with it either so i have to do it myself

technically a singaporean passport doesnt need a visa to enter the philippines so an expired student visa isnt 100% bad right?

in my past experience, they made me downgrade my visa anyway bc it expired or something a few years back

this post is a half rant half question (abt penalties etc) lol im really tired about the inefficiency esp of my school with regards to document requesting and their incessant need for me to do internship under them (so they can get more money from my parents with subpar payout training-wise)
