No, you're wrong too. The 20k is the Master's cap, only applicable to students who did a Master's or above in the US. Cap exempt refers to H1bs granted to US/State employers, who can get H1bs for employees without any cap whatsoever, and at any time of the year.
thanks, i see. So, MS can't get them really.

This. Cap exempts are usually PHDs and literal medical doctors.
