I sent an email to DPS on June 4 asking this question:
With the change by HB 3142, will all existing NSA licenses automatically allow the holder to carry either SA or NSA after this becomes effective?
Or, does this only apply to license issued after the effective date of the change?
Answer:
HB 3142 states the changes affect a license issued on or after the effective date. I just checked and it does not appear to have been signed by the Governor at this time. Once it has been signed, the effective date is noted as September 1, 2013.
