Licensing or membership is required to practice many professions or to benefit from the services of professional organizations. Mali has major professional organizations that tend to exert influence on political decisions related to their sectors. Some notable professional organizations include the Ordre des Experts Comptables in the accounting field, the Ordre des Architectes in the architecture field, the Ordre des Pharmaciens for pharmacists, and the Ordre des Avocats for lawyers. Starting a commercial bank or microfinance institution in Mali requires approval from the central bank. The U.S. Embassy in Bamako advises U.S. citizens to be aware of specific requirements for different sectors. Belonging to professional organizations is helpful in obtaining information and negotiating commercial partnerships.
