What is a third country national?

A third country national is someone who is not a citizen of the country where they are currently residing or working. This individual is also known as a non-national or alien. Third country nationals may have entered the country on a temporary or permanent visa, work permit, or through other legal means. They usually hold a passport from a different country than the one they are residing in and may face additional regulations and requirements compared to citizens or nationals. Some third country nationals may be categorized as refugees, seeking asylum in a different country due to persecution, war, or conflict in their country of origin. Others may be immigrants trying to improve their economic or social standing by moving to a different country.
