What term describes companies organized under the law of another country, such as Mexico?

The term that describes companies organized under the laws of another country, such as Mexico, is "Alien Insurer." In the insurance industry, an Alien Insurer is defined as an insurance company that is established according to foreign laws, specifically outside the country in which the insurance is being sold. This classification highlights the international aspect of the insurer's operation and the regulatory environment it must navigate.

In contrast, a Domestic Insurer refers to companies that are chartered and operate within the same country where they are offering insurance. A Foreign Insurer is typically associated with companies that are based in another state within the same country (for example, a company based in California selling in Texas). Lastly, while "International Insurer" might imply a company with a global presence, it is not the formal legal classification typically used in the context of U.S. insurance terminology. Therefore, the designation of Alien Insurer is the most accurate in describing insurance providers operating under the jurisdiction of a different country.
