Step-by-step explanation:
The most common way to gain citizenship if you were born in another country is through the naturalization process. Naturalization is the legal process by which a non-citizen becomes a citizen of a country. It usually involves fulfilling certain requirements such as having a specific period of continuous residence in the country, demonstrating knowledge of the country's history and government, and passing a citizenship test.
