Wyoming's concealed-deadly-weapon offense statute excepts a person who does not hold a Wyoming-issued permit but 'is a resident of the United States and otherwise meets the requirements specified in paragraphs (b)(ii) through (vi), (viii) and (ix) of this section and possession of the firearm by the person is not otherwise unlawful.' Combined with the permit eligibility criteria, this means any non-prohibited U.S. resident aged 21 or older (or 18 with qualifying military service via 18 U.S.C. § 922(g) eligibility) may carry concealed without a permit.
"The person does not possess a permit issued under this section, but is a resident of the United States and otherwise meets the requirements specified in paragraphs (b)(ii) through (vi), (viii) and (ix) of this section and possession of the firearm by the person is not otherwise unlawful."
