Disaster Work in Texas -
There's a lot of misinformation out there and some employment scams already surfacing. You must be a licensed security officer already in some state to qualify under the Texas rule suspension.
Only a security officer currently commissioned in Texas or another state may perform duties as an armed security officer in Texas under this exemption.The security officer must submit documentation from the licensing agency of the particular state establishing the individual has passed a state and federal criminal history background check and is not federally disqualified from possessing a firearm.
