retraining overseas

for those who have retrained overseas, how did it work for yall? did yal just tdy to tech school and come back or was is tdy enroute to pcs?

if it was a tdy enroute to pcs, when did you get your orders? how did you go about doing it? and how did you make sure that everything would be covered by the af?

my class starts less in 20 days, and i have no assignment or orders and im freaking the fuck out. formal training has confirmed with me that i should be doing a tdy enroute to pcs. and afpc just wont load an assignment and mpf keeps telling me there is nothing they can do.
