naturalization

Use the noun naturalization to describe what happens when someone becomes a brand new citizen of a country.

If you're born in one country but want to become a citizen of another, you'll have to go through the process of naturalization. There are certain rules and processes involved in naturalization, depending on the country, but you usually have to live there for a certain number of years and swear an oath of loyalty. When biologists use the word naturalization, they're talking about moving plants or animals to a new place where they can thrive.
