The international organization is an umbrella term that covers both intergovernmental organizations (IGOs) and international nongovernmental organizations (INGOs). IGOs refer to formal institutions whose members are predominantly states. INGOs, on the other hand, have a different composition of membership from IGOs as their members are mainly individuals or groups of individuals rather than states.

Legitimate transnational actors from a country can be transnational companies, political parties, or NGOs. Legitimate actors usually engage with IOs in the management of international relations. As a legitimate type of transnational actors, transnational companies (TNCs) play a relatively greater role in international politics today. They primarily lobby foreign governments in several ways; they can indirectly ask their own government to put pressure on a foreign government, try to affect the target government through IOs, or directly reach its diplomatic missions or ministries.

Non-legitimate transnational actors can also produce an impact on international politics. They generate serious problems for states such as criminal financial flows, criminal trade, or illegal trafficking. Because of this, states nowadays individually or collectively are trying to find legal solutions toward blocking the illegal activities of these groups.
