Special provisions on American naturalization:

I. Age limit

According to the immigration law, a citizen applicant must be at least 18 years old. However, there are two exceptions to this clause.

1. Applicants for naturalization must reach the legal age. There is no age limit for soldiers who serve in wars between the United States and foreign countries.

2. If one or both parents of minor children are American citizens, they can apply for naturalization through their parents.

Second, legally obtain permanent resident status.

Applicants must obtain a green card through legal channels. Non-citizens are not eligible to apply for citizenship if the way or means of obtaining a green card is illegal. Some people were found to have problems and illegitimacy in their green card status after obtaining citizenship, which led to the loss of citizenship;

Third, we must recognize the principles of the American Constitution.

Promote good order and happiness in America. American courts interpret "recognition" as "no hostility". Therefore, people who are hostile to the Constitution or advocate overthrowing the government are not considered to have "good moral character".
