Got a letter in the mail telling me I should renew. It is not due till Apr 2020 so I have heard horror stories about the process so I submitted my paperwork to renew. Waited a couple of weeks and received another letter telling me I forgot to enclose my DD form 214 showing I was honorably discharged and that I was a veteran. Even though it showed I was a veteran on my current CHL and also shows that I am a veteran on my drivers license which I sent in the first submittal. I resubmitted the requested paper work and now just waiting to hear from them again.
