TCN (Third-Country National)

A Third-Country National (TCN) is someone who is not a citizen of the country where they are currently working or residing, nor a citizen of the country that hired or authorized them. For example, if a person from India works in the United States but is neither a U.S. citizen nor an Indian citizen, they are considered a TCN. This term is often used in employment, immigration, and security contexts to identify individuals from outside the specific regions involved. TCNs may face different visa, security, or legal requirements compared to local or regional nationals.
