student rate at conferences If the student status of a conference participant expires between the registration for the conference and the conference itself, is it typical that the person still pays the student fee (rather than a higher regular participation fee)?

EDIT: I reject "individual factors", "personal values" and "a certain person's preferences" as reasons why the question has been put on-hold: there is nothing preferential, nothing that would concern an individual here. The question couldn't care less about your personal values, my dear reader. The question is about how past conferences handled it typically, i.e., simple facts.
Yes.

The purpose of student discounts is to encourage people with a limited income and limited funding to participate.  Recent graduates are in that category.

Most students presenting at conferences are PhD students.  Usually, PhD students are not sure when they will finish their degree.  It's perfectly normal for a PhD student to register for a conference as a student, and there's no reason to change their registration if they happen to graduate before the conference occurs.

I've never seen a conference verify any information I have sent to them.

(Conferences are not publications in my field.)
