Randy,
I can appreciate the frustration with putting in lots of work and it hasn’t paid off so far. If this is truly your dream, then don’t give up. An age waiver is nothing more than a piece of paper, and if you are the right fit for a unit, the unit will go to bat for you and convince their upper levels of leadership that this age waiver is legitimate and worth their signature.
My advice to you would be to set realistic expectations and find the spots where you have the best odds. That means searching out units that have fewer applicants to their hiring boards. Focus on units who have a mission focused in border security, possibly helping with Customs and Border Protection, so you can play that experience up. Lastly, although expensive, I do think that having as much flying experience as possible as an older candidate will make you more intriguing to units. You want to stand out from the crowd, and alleviate any areas where a hiring panel can eliminate you from contention.
Hopefully this helps steer your search a little and you can gain some traction. Best of luck!
