Have you spoken to your ROTC Commander or NCO advisor?
After completing all Air Force ROTC and academic degree requirements, contracted cadets are either cadets in the Professional Officer Course (POC) and scholarship cadets then accept a commission as second lieutenants in the Air Force.
The length of your initial service commitment depends on your career. Most cadets make a four-year, active duty service commitment. Pilots make a 10-year, active duty service commitment and both Combat System Officers and Air Battle Managers career field make a six-year service commitment.
Nursing graduates accept a commission in the Air Force Nurse Corps and serve four years on active duty after completing their licensing examination.
I hope this helps!
