Here's something than can help. Isha considers their USA chapter a "non-profit" / "non-religious" charity, and are currently listed in the Better Business Bureau as having "no rating". Unless a company is proactive in submitting info to BBB, BBB only researches them if there are enough requests. Maybe you guys can put in some requests? I just did. :)

Here's their address:

Isha Foundation, Inc.
191 Anthony Drive,
McMinneville, TN, 37110

Here's the form where you can inquire about a charity with the BBB:
[charityreports.bbb.org]

Here's a link to their current BBB listing (B-):

Also, here's a link to Isha's most recent annual report (2006):
