Air Force Msgt to Army Warrant Officer, will 20 years TIS be a problem?

I'm an Intel WO and know that 352S is low density, but also currently short of being full strength. While you're beyond the ideal accession point, I would say you stand a pretty good chance of getting your AFS waiver approved. Check the recruiting website previously posted and, if you still have questions, reach out to the POC listed on there for the field you're seeking. They will be the best resource and help to avoid incorrect answers based on hearsay. The only way to guarantee not getting selected is to never submit a packet. Good luck!

MSgt Hazel - there was a 49 year old 30 year TIS CSM in my WOCS class back in 2008. I believe the TIS is waiverable, of course depending upon the Army's needs at the time of your packet submission. I certainly wouldn't let it discourage you from applying! We can always use good, dedicated people with your level of experience! Good luck.

As someone who has participated on several Army Warrant accession boards (I am a retired CW5, 352N) I have to say that you are way past the "regular" accession point (minimum SGT/E5 with <10 years AFS), and asking for a 10-year waver would be unique; getting one would be highly unusual. We generally like to get 10 years of Warrant service from a candidate, and that would put you past the 30-year mark. That said, I'd give it a shot, all they can say is no.
Additionally, there is the issue of your making it through the Warrant Officer Candidate Course (WOCC) at your relatively advanced age - presume you are in your mid-to-late 30's.
Presume that you have looked at the prerequisites (http://www.usarec.army.mil/hq/warrant/prerequ/
WO352S.shtml) and have met the AF-equivalent course requirements.
On another subject, I suspect that as a AF MSgt with 20 years service, DoD, NSA or AFSS would snap you up as a civilian (GG-11/12) fairly quickly - which is more money.
