Limited Job Opportunities

Hello

I’m 22 f and currently looking to enlist with the USAF. I’m speaking to a recruiter this Tuesday in hopes of getting the process started. Recruiter told me that the Air Force is only looking for Electrical/Mechanical engineering , Security Forces, Special War Fare, or Linguist career fields. Is this true? And to be honest out of everything Linguistics is what stood out to me, but I do want to go in for anything in Aviation. Since it seems like Aviation is not available right now will it ever open up in the near future?

My question is, Does the Air Force open Jobs every 3 months or how does it work?

I’m not planning to ship out until February 2025 anyways just because I want to lose some weight and get fit beforehand.

Any information would really help. I’m sorry in advance if I don’t make any sense. :/
