European countries encourage men to immigrate to the United States.

If your boyfriend has got a green card, it is his freedom to get married in China, and his green card will not be cancelled just because he is married. Unless he is still in the process, he can't get married during this period.

As for the conditions of naturalization: more specifically, I will copy others.

1, 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. First of all, the naturalization applicant must reach the legal age. There is no age limit for soldiers who serve in wars between the United States and foreign countries. Second, if one or both parents of minor children are American citizens, they can apply for naturalization through their parents.

2. 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 who have obtained citizenship have been found to have problems with their green card status by the immigration bureau, which is illegal and leads to the loss of citizenship.

3. Applicants must have lived in the United States for five consecutive years before submitting their application for naturalization. "Continuous residence" means staying for five years without major interruption. "Living" means living and working in the United States, owning certain personal property, owning a car registered in its name, paying personal income tax and so on. However, if the spouse of the applicant is an American citizen, the applicant only needs to live in the United States for three consecutive years. However, if the spouse of a non-citizen divorces before the expiration of three years, or the spouse of an American citizen dies, the special rule of continuous residence for three years does not apply. However, if the applicant obtains a green card according to the provisions of the Anti-Abuse of Women Law, he can still apply for naturalization according to the special provisions of continuous residence for three years, regardless of whether he is divorced or not. The immigration law allows you to apply for naturalization three months before the expiration of your continuous residence. Therefore, applicants can apply for naturalization after four years and nine months of continuous residence or two years and nine months. According to the law, leaving the United States for no more than six months is generally not considered as an interruption of continuous residence. If you leave the United States for more than half a year but less than one year, you may be deemed to have interrupted your continuous residence by the Immigration Bureau, unless the applicant proves that you have no intention to give up your continuous residence. Leaving the United States for more than one year will interrupt your continuous residence. If the applicant is an overseas employee of a U.S. government department, an American company or an international organization, the time spent abroad may not be considered as the interruption of continuous residence, but one of three conditions must be met: a) he has lived in the United States continuously for at least one year after obtaining a green card and must be employed by a U.S. government department or an American research institution recognized by the Attorney General; B) employed by an American company engaged in foreign trade or business, or c) employed by an international organization of which the United States is a member according to international treaties or laws. The parties concerned must submit the N-470 form to the Immigration Bureau to apply for continuous residence time, and spouses and children of overseas employees can also apply for continuous residence time at the same time.

4. Meet the actual stay time and requirements. Naturalization applicants need to prove that their actual residence time in the United States is not less than 30 months. Spouses of American citizens need to prove that they have actually lived in the United States for not less than 18 months. Naturalization applicants who maintain continuous residence time after the above N-470 form is approved by the Immigration Bureau must also prove that their actual residence time in the United States has exceeded 30 months or 18 months.

5. You must live in the area where the naturalization application is submitted. According to the immigration law, the naturalization applicant must live in the state or region where the N-400 form is submitted for three months before taking the naturalization test or interview in that state or region. If the naturalization applicant lives in multiple states in turn, the state he or she belongs to depends on the state where he or she submits the federal personal income tax and state tax forms.

6. Must have good moral quality. According to the law, naturalization applicants can only apply if they have good moral quality within five or three years after obtaining a green card, but the law does not specifically define what good moral quality is. Generally speaking, good moral character can be interpreted as that the applicant has reached the average moral level of ordinary citizens in the community where he lives, without the need for extremely lofty or highest moral integrity. For example, people who do not have "good moral character" usually include habitual alcoholics, people with specific criminal arrest and conviction records, professional gamblers, people who have been sentenced to imprisonment 180 days or more, people who have committed perjury, and people who have been convicted of "felony" as defined by the immigration law. In addition to the above-mentioned personnel, some applicants may also be identified by the Immigration Bureau as not having "good moral character". For example, in recent years, some China people have encountered difficulties in applying for naturalization because they have not registered for selective service. 1980, the United States resumed the "selective service" registration system, stipulating that all men aged 18 to 26 must register. Some people in China don't understand the registration system and didn't go through the registration procedures. Therefore, immigration officials decided in the naturalization interview that they did not have good moral quality.

7. We must recognize the principles of the American Constitution and promote good order and happiness in the United States. 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". At the same time, when the United States is at war, deserters or people who evade military service in the army will also be considered immoral.

8. Basic English level. Since the beginning of the 20th century, naturalization applicants have to pass exams to prove their ability to read, write and speak everyday English. Immigration officials usually ask applicants questions in English and ask them to write simple English words. If the naturalized applicant cannot read, write and speak English due to physical disability, he can apply for exemption from the English proficiency test. The applicant must issue a certificate issued by a doctor. In addition, applicants who are over 50 years old and have lived in the United States with a green card for 20 years, or over 55 years old and have lived in the United States with a green card for 15 years, do not need to pass the English proficiency test.

9. Understand the basic knowledge of American history and government. Questions about American history and basic knowledge of government prepared by immigration officials come from federal textbooks. Naturalization applicants need to master the basic knowledge of American history and government. Even if some applicants are exempted from the English proficiency test, they must take the test of American history and basic knowledge of government. Immigration allows translators to be present to help with the test. However, if the applicant can prove that he can't take the exam because of his physical disability, he can also request exemption. In addition, naturalization applicants over the age of 65 who have lived in the United States for 20 years and have green card status will receive special care in the exam.

10 must swear allegiance to the United States. All applicants for naturalization must swear allegiance to the United States. However, if the applicant cannot support the possession of weapons or military service because of different religious beliefs or moral values, his oath can be slightly revised. Minor children are too young to understand the oath, or people with physical or mental disabilities can request exemption from the oath obligation. After the 9- 1 1 terrorist attacks in the United States, Americans attached great importance to homeland security and greatly strengthened their preventive measures against foreigners. Therefore, it is becoming more and more important for foreign permanent residents to apply for naturalization. Joining American citizenship will bring new opportunities, opportunities and responsibilities. It also makes life in America safer.

The most important thing is nothing more than the first four. As for arranging citizens by relatives, it is about one year.
