Understanding how international insurance companies operate in the United States is crucial for anyone navigating cross-border risks. This guide clarifies the role of alien insurers—companies based in a foreign country that are legally licensed to conduct business in the U.S.
We will explain how these companies are regulated, define key concepts like “admitted” versus “surplus lines,” and provide a directory of prominent alien insurers authorized to offer coverage in the American market.
What is an Alien Insurer?
In the context of United States insurance regulation, the terminology is very specific:
- Domestic Insurer: A company licensed in the same state where it is incorporated (e.g., a California-based insurer licensed in California).
- Foreign Insurer: A company licensed in a state other than the one where it is incorporated (e.g., a Texas-based insurer licensed in California).
- Alien Insurer: A company incorporated and domiciled in a country outside of the United States but licensed to operate in one or more U.S. states.
This guide focuses exclusively on these alien insurers.
How Alien Insurers Are Regulated in the US
For an alien insurer to operate legally in the U.S., it cannot simply sell policies from abroad. It must undergo a rigorous regulatory process to ensure it is financially stable and complies with local laws. There are two primary ways they participate in the market:
1. As a Licensed (Admitted) Insurer
To become an “admitted” carrier, an alien insurer must be licensed by the Department of Insurance in each state where it wishes to sell policies. This process is demanding and requires the insurer to:
- Prove significant financial solvency and maintain adequate reserves.
- Adhere to all state insurance laws and consumer protection regulations.
- Contribute to state “guaranty funds,” which help pay claims if an insurer becomes insolvent.
Many alien insurers achieve this by establishing a U.S.-based subsidiary that is treated as an American company for regulatory purposes.
2. As a Surplus Lines (Non-Admitted) Insurer
For unique, high-risk, or complex coverages that admitted insurers may not be willing to underwrite, the surplus lines market provides a solution.
Alien insurers can operate in this market without a state license, but they must be on an approved list maintained by the NAIC (National Association of Insurance Commissioners). The NAIC’s Quarterly Listing of Alien Insurers identifies companies that have met strict financial requirements, making them eligible to provide surplus lines coverage.

View Insurer Specialty Lines & Global ReinsuranceFrequently Asked Questions (FAQ)
Q1: What is the NAIC and what is its role with alien insurers? The NAIC (National Association of Insurance Commissioners) is a standard-setting organization for US insurance regulators. While it does not regulate companies directly, it maintains a critical list of approved alien insurers that are eligible to operate in the surplus lines market, ensuring they meet robust financial standards.
Q2: Is it safe to buy a policy from an alien insurer? Yes, provided they are properly credentialed. If they are a licensed (admitted) carrier in your state, they are backed by the state’s guaranty fund. If they are an approved surplus lines insurer on the NAIC list, they have met high financial solvency requirements, though they are not backed by state guaranty funds.
Q3: Why would a US resident need an alien insurer? Most US residents will be covered by domestic or foreign (US-based) insurers. However, you might interact with an alien insurer for highly specialized needs, such as international travel insurance, marine cargo coverage, large-scale corporate liability, or other risks not covered by the standard market.
