Sounds to me like AYA should do what ever they do when taking them to shows,if it involves a distributor representative then that the way to do it.
From the ATF site;
http://www.atf.gov/firearms/faq/unlicensed-persons.html#shipping-firearms-additionalQ: May a nonlicensee ship firearms interstate for his or her use in hunting or other lawful activity?
Yes. A person may ship a firearm to himself or herself in care of another person in the State where he or she intends to hunt or engage in any other lawful activity. The package should be addressed to the owner. Persons other than the owner should not open the package and take possession of the firearm.
The term "unlicensed person" is shown in several other places as "non alien".Alien s would require a "State of residence"
They may have FFL of course,if so they can ship them to themselves as well.
: May aliens legally in the United States buy firearms?
An alien legally in the U.S. may acquire firearms if he has a State of residence. An alien has a State of residence only if he is residing in that State and has resided in a State continuously for at least 90 days prior to the purchase. An alien acquiring firearms from a licensee is required to prove both his identity, by presenting a government-issued photo identification, and his residency with substantiating documentation showing that he has resided in the State continuously for the 90-day period prior to the purchase. Examples of qualifying documentation to prove residency include: utility bills, lease agreements, credit card statements, and pay stubs from the purchaser’s place of employment, if such documents include residential addresses.
