Advice: joining the military in Grad School

BAR21

Hello, I want to join the Air Force, but i do not make weight right now. I have like 60 lbs to lose. I just finished my under grad and decided to go to grad school while I lose the weight. I got a job that will pay for my classes and somewhere to stay. My question is, is it okay to join while I’m in grad school. I know a lot of people join to pay for their undergrad and just for the money, but I really want to go into the cyber security field.
