An ethnic interest business or ethnic lobby, according to Thomas Ambrosio, is an advocacy group often a foreign policy interest group develop along cultural, ethnic, religious or racial configuration by an ethnic group for the purposes of directly or indirectly influencing the foreign policy of their resident country in support of the homeland and/or ethnic kin abroad with which they identify.
According to Ambrosio, "like other societal interest groups, ethnic identity groups setting formal organizations devoted to promoting chain cohesiveness together with addressing group concerns." While many formal organizations established by ethnic identity groups are apolitical, others are created explicitly for political purposes. In general, groups who seek to influence government policy on home or foreign issues are pointed to as advocacy groups. Those interest groups established by ethnic identity groups are returned as to ethnic interest groups.
