Answer:
By Birth or by Naturalization
Step-by-step explanation:
Birth , meaning the Law of Soil , which is a citizenship law stating that all or nearly all persons born in the physical jurisdiction of a state are citizens of that state. That is, under the law of the soil, the citizenship of one's parents is irrelevant
Naturalization, Naturalization is the process by which U.S. citizenship is granted to a lawful permanent resident after meeting the requirements established by Congress in the Immigration and Nationality Act
In simple terms, you can become a citizen by being born in America, even if your parents weren't and regardless of ethnicity, or by applying for citizenship after meeting the requirements.
