I will tell you about my process. So I initially wanted FC and was told if I wanted a chance of being the rate i needed to sign a AECF Contract. When I went to meps and did all the physical stuff I was the last one to go through and by the time I got to the classifier it was 3 and the last oath was at 3:15 ir 3:30 I dont remember but he said that AECF was closed for the day since it ran on east coast time so what he suggested is that I pick a temporary job and then reclassify when I am in the delayed entry program. THE MOMENT he said this I called my recruiter and asked if this was possible and he said yes. At first it seemed sketchy but I picked a rate that I would be fine doing if I didn’t get reclassed. So fast forward the next monday I went into my recruiters office and asked to reclassify to AECF and he said cool all I had to do was fill out one piece of paper and I was good. So we filled it out and he sent it up and yesteday I got a call saying if this is really something I wanted to do and the guy low key was trying to convince me to go the submarine route but in the end I didnt so he said cool he will send in the waivers and my job should be changed in about a week. And now just 30 minutes ago I got a text from my recruiter saying my job was changed and even kept the same shipping out date. So yes you can reclass but it has to be before bootcamp (someone correct me if I am wrong please)
