And the big answer is... "it depends".

First of all, you're a member of Alpha Psi Omega for life.  Once you're initiated, you go into our files and you're set.  There is no mechanism to remove someone from those files.

For the local organization, it's very much chapter-to-chapter.  If they want to recognize your Alpha Psi membership by just letting you in to their chapter of Delta Psi, they can do that.  If they want to make you pledge again, they could do that.  I haven't heard of any chapters simply not recognizing someone's prior membership when they transfer, but I suppose it could happen.

The only REAL answer: go and talk to them and figure out what the local Constitution allows for and see what the members want to do.  (I wouldn't be surprised if the answer is "nothing" and "make it up".  That's pretty common.)

It should be noted that if you wanted to "officially" join the DPO Cast at your new school, you'd have to pay the extra money to join their Cast file.

I found that out when I wanted to be an official member of my graduate school's Cast.  But that was back when we had slightly cheaper dues.  This call is up to you.

Now and Forever!
