I have a cert. form AZ and Maryland so do any of those count?
Hi as of right now the Az nor Maryland couont toward any training exemption. You'd still need the full 16 hours of training. This excluds the "vehicle exemption for non residents" assuming you either reside in Maryland or AZ.
As of right now the only things that count for training exemptions are are follows:
llinois Hunter Safety Course 4 hours
Utah Concealed Carry 4 hours
Florida Concealed Carry 4 hours
Nevada Concealed Carry 4 hours
Missouri Concealed Carry 4 hours
Kentucky Concealed Carry 4 hours
Michigan Concealed Carry 4 hours
Chicago Firearms Safety Course 4 hours
NRA Basic Pistol 8 hours
NRA Personal Protection in the Home 8 hours
NRA Personal Protection Outside the Home 8 hours
Active, Retired, or Honorably Discharged member of the United States Armed Forces 8 hours
Prior Law Enforcement/Corrections Officer Firearms Training as detailed in 430 ILCS 66/75(J) 8 hours
Have they determined which states whose residents they will accept non-resident applications from?
I have not seen any determination just yet. It is safe to say that we will find out in the coming few months as people begin applying. If I do come across further information I will post it. Having said that, "substantially similar" has recently been defined, but they haven't stated which states are substantially similar.
