Berto,
I dug up the list of foreign countries which grant US trained DOs unrestricted practice from the AOA Yearbook 1996 and Italy was among them.
In 1996, in addition to Italy, the following countries granted US trained DOs full practice rights:
Argentina, Austria, Cameron, Canada (some provinces only), Cayman Islands, Chile, China, Columbia, Costa Rica, Ecuador, Finland, Germany, Greece, Guyana, Israel, Italy, Liberia, Luxemburg, Micronesia, Nepal, Nigeria, Panama, Russia, Tanzania, United Arab Emirates, Vietnam, Saudi Arabia, Sierra Leone, Sweden, Zambia.
The following countries did not allow US trained DOs to practice at all:
Aruba, Bahamas, Belize, India, Ireland, Mexico, Malaysia, Morroco, Singapore, Spain, Switzerland, Taiwan, Uganda.
The following countries allowed US trained DOs to practice only OMT:
Australia, Barbados, Bermuda, France, Great Britain, Jamaica, New Zeland, Norway, South Africa, Zimbawe.
Keep in mind that this data is from 1996, so things may have changed. If someone has a more current list, please post it for everyone's benefit!
