Just as an added note, the blog at scoutingmagazine.org, "Ask Brian" is one of the best sources for information out there. Many of my questions have been answered after a quick sweep of his posts. Just like searching here! Hope this is helpful.
Wow ... this represents a gross misunderstanding of both the BSA uniform and the awards mentioned.
The BSA offers no awards or insignia based on a boys heritage or ethnicity. The "Asian American Award" does not exist. Rather, the items referred to are knots representing larger awards given for outstanding service to, and promotion of the BSA among, certain communities. There is one for serving predominantly Asian communities, one for inner city groups, one for Latin American/Hispanic communities ... even one for serving Native American youth. And even more to the point, the BSA just recently created one single square knot representing all such awards together, so Scouters wearing a knot for service to Latin communities wear the same knot as those recognized for service to inner-city youth or disabled groups.
These awards are not given in recognition of heritage, but rather for adults who have done service for specific communities amongst whom Scouting is less prevalent yet could be of positive impact. They are not worn by Scouts because they are not awarded to them. They are given to Scouters who work through the BSA in service to communities in need. Also they are not earned, they are awarded, with the exception of those who work with disabled communities, in the which case it is again for adults, and again, in recognition of service and meeting stringent requirements.
The creation of this "award" seems like a very reactionary move in response to a problem that ...... never existed. And as has been noted, they cannot implement official uniform items without the approval of National.
Unless it goes on the right pocket, with "temporary insignia," of course.
The Latin Scot's post in Can parents serve as merit badge counselors for their scout? was marked as the answer
