What are the requirements for American immigrants to apply for naturalization?

1. You must live in the United States continuously for five years after obtaining permanent residency. This is the minimum residence period for naturalization. Within five years, you can't leave the United States for more than six months in a row. If it is more than half a year, you must provide proof that you have no intention of giving up the right of abode in the United States. Therefore, it is necessary to extend the naturalization application time accordingly and recalculate the residence time in the United States. Before applying for naturalization to the US Immigration Service, you must live in the United States for at least 3 years, at least half a legal period. 2. A foreign citizen who marries an American citizen must remain married for two years before both husband and wife can apply for naturalization to the Immigration Bureau. The new immigration law stipulates that foreign citizens who are married to American citizens or permanent residents should apply for naturalization as soon as possible as long as they meet the conditions for applying for American citizenship, so as to become American citizens as soon as possible and enjoy all the rights as American citizens. But the prerequisite must be a marriage relationship that lasts for more than two years. 3. When applying for naturalization, you must live in the United States for the last six months of five consecutive years and live in the local state or city for at least six months. 4. Applicants for naturalization must be at least 18 years old. Foreigners under the age of 16 who have permanent residency in the United States, whose parents have acquired American citizenship, can automatically acquire American citizenship with their parents. However, children aged between 16 and 18 must apply for naturalization independently. If the child is under the age of 18, and one parent is an American citizen and the other parent is a foreigner, before the child reaches the age of 18, the parent with American citizenship can apply for naturalization on his behalf.
