It's about a 6 to 12 months wait for swimmer school right now. You'll spend 6 weeks at the Ramp up/ airman program then 18 weeks of A-School, Both are now at E-city. I'm sure you are but be prepared, its a long 24 weeks of swimming.
We have QA's but your Quals won't carry over. Only thing that will carry over is your EMT qual and that get you out of 7 weeks of EMT School if you don't let it lapse.
Why do you want to become a USCG Rescue Swimmer?
