Gadolhadofi,
It’s hard for me to tell you, because I don’t personally know any Lubavitchers who are in college (though I assume that there are some).
Again, the Rebbe was adamantly against any Jew (not just Lubavitchers) going to college (aside from very rare individual exceptions). Therefore, this is considered very taboo in Chabad.
I guess a chossid who would do this would be viewed like anyone who does something very wrong.
Google: “chabad dot org no college” for many letters (the less fiery ones) of the Rebbe (mostly to non chassidim) on the matter.
(For parnosa, there were certain conditions when the Rebbe allowed it bedieved, such as only AFTER MARRIAGE, etc.)
