Erm.. not entirely sure to be honest, I know you can change on the J1 Academic after 30 days, but because the ICPs are only there a couple of months, it might be pointless changing halfway through?! xx
unless you have like a proper reason, one of my roomates reacted badly to the chemicals for custodial so he was moved to be a runner at the all stars
I have only heard of people changing because of medical reasons or if they fail there assessment. i was changed from f&b to ops as between my interview and getting out there i got a bad back injury and can't bend or lift heavy items, and even then it took nearky six weeks for me to be moved.
