There are many things that play a factor into getting in as an officer. It is extremely competitive when it comes to officers. What kind of degree do you have? Technical Degrees are highly preferred. Medical degrees are preferred too. If you have any other degree, it makes it hard to get in. They look at your GPA. If you have below a 3.5, it will make it hard to compete against other applicants. They look at law violations, drug use, age, height and weight, community service, sports, volunteer work, clubs, etc.
The recruiter knows if you would have a competitive package or not. Trust me, if he thinks he has a chance of getting you in as an officer, he would put in the package. If he thinks you dont have a chance being competitive, he will tell you to look into enlisted.
Being enlisted is a good gig. With your education, you will come in at a higher pay grade. Once you complete technical training, you will be awarded an AA degree in applied science because of your previous college experience. They have over 60 different degree programs in applied science.
There are many commissioning programs available to enlisted people with degrees. At your 1 year mark as enlisted, you can apply for a commissioning program and have a good chance of getting accepted. The Air Force is just like any other corporation, they would rather promote from within thier company as opposed to taking in a stranger off the streets.
One thing people tend to forget is that joining the Air Force is not a right or a guarantee. People think they can demand whatever they want and expect the recruiter to bend over backwards to give it to them. The Air Force will tell you the same thing that any major corporation would if you walked in demanding a job. Try to demand a job position with Microsoft, boeing, lockhead Martin, or any of the other high tech companies. They will tell you to take a hike. The Air Force is no different. They are responsible for multi million and billion dollar assets. They arent going to let you do whatever job you want just because you demand them too. If you work with the recruiters, they will work with you. If you give them attitude or demand things, they wont want you in the Air Force.
ADDITIONAL UPDATE:
After your update, I can see why the Officer recruiter told you to look into Enlisted. Your GPA and Degree just arent competive. You wouldnt have a chance against the 3.8-4.0 students with an Electronical Engineering degree and such.
Enlisted would be a good opportunity for you. They have a program that you could apply for at your 1 year mark called the Airmen Education and Commissioning program. It use to be for getting a BA degree but they just opened it up for people with BA to persue a Masters. The program allows you to go to school full time as an AF member. It pays for your tuition, books, housing, and food. They will also pay you just over $1900.00 a month as a E-5 while you attend college. You would have to go to a college with the AFROTC but those are everywhere. They would have you do Officer field training during the summers. Once you graduate with your Masters, you would be an officer in the AF with a masters free of charge.
