As the programs fill up the remiaing seats they are less inclined to offer choices for interview dates that they did earlier when they started interviews. Since they have a long waiting list that you would be competing against I would suggest that you be extra well prepared for the January interview. Even if they don''t accept you right away, it would be to your advantage if you are put on waiting list.
So many getting accepted to multiple schools and withholding seats while waiting to hear from their top choice resulted in longer and longer time on the waitlist for those really wish to get accepted to these programs
Most people who chose to stay in their state for the PA program decide on the basis of tuition fee and the fact that they may not have to rent an apartment If you have decided to move to another state you will probably receive job offers after doing your rotations there. I also suggest to confirm PA school Accreditation status & reason eg why they are on probation as a clue to find out if they are on solid ground
