When do Reserve Soldiers get paid while attending an ASI school?

Orders less than 8 days are input when the certified orders are received back with your finance POC (UA or RPAC). You will be paid on the next pay cycle which is usually 10 days later.

Orders that are more than 8 days but less than 30 are input the day the orders start and you'll be paid on the last day of the orders (or within a couple of days)

Orders that are more than 30 days are input by the school house and you'll fall into the 1st and 15th pay cycle.

If your ordersl is over a certain amount of days the can pay you on the first day of orders if it is less than a certain amount of days they can't put in pay till you return from the school. If you are there for three weeks then your UA shuld be able put in your pay now.
