After all, it is responsible for all immigration processing projects, so you may find it very complicated. The US Immigration Service is the largest and most complex administrative system in the United States. Here is a brief introduction to its specific structure.

(1) Office of the Director of the United States Citizenship and Immigration Services. The administrative director of the Immigration and Naturalization Service is the Director. The Attorney General authorizes the Commissioner of Immigration to enforce and enforce the Immigration and Nationality Act and all other laws relating to immigration, naturalization, and nationality.

(2) Office of the Deputy Commissioner of the United States Citizenship and Immigration Services. This office is authorized to exercise all the powers and duties of the Director except those required by law to be performed personally by the Director. The Deputy Director assists the Director in formulating and implementing the Bureau's policies and plans, and provides leadership and guidance to all Bureau agencies. The Deputy Director also performs tasks assigned by the Director from time to time. In addition, the deputy director has four administrative assistants to each director, responsible for planning, execution, policy and programming.

(3) Office of the United States Citizenship and Immigration Services. This office is responsible for policy implementation. The basic function is to oversee and coordinate all practical enforcement actions related to the enforcement of immigration laws, including the refugee application process and the adjudication of family-based immigration petitions filed by citizens and lawful permanent residents. In addition, the office leads the work of the directors of the East, Central and West bureaus and the Office of International Affairs.

(4) Assistant to the United States Citizenship and Immigration Service. The main function of this office is to guide and coordinate the overall policy planning work of the USCIS.

(5) USCIS Management Office. This office is responsible for planning, developing, directing, coordinating and reporting on USCIS management plans and work, revising global administrative regulations, and coordinating all accounting, personnel, administrative and information management functions. In addition, the office provides leadership and direction to the local agencies and departments listed below.

After understanding their division of labor, we can basically understand their work content. U.S. visa officers are generally divided into two types. One is to prevent you from settling in the United States, such as when you apply for a tourist or study visa.

The decisions made by the visa officer are in compliance with U.S. law. There is a provision called 214B in the U.S. immigration law. The meaning of the clause is that every US visa applicant has the tendency to immigrate.

Unless the applicant can prove that he or she has no intention to immigrate, and the domestic binding force is very strong, and will not stay in the United States for a long time, the main reason why most applicants are rejected is that the visa officer believes that they may stay in the United States.

The other is the immigration officer. Their job is to let you settle in the United States. The U.S. immigration officer attaches great importance to the applicant's financial ability. After all, this can indirectly reflect your spending power in the United States.

Therefore, many applicants always have the mentality that the more the better when preparing materials on financial ability, and this information often accounts for half of all application materials.

But this is actually a misunderstanding. The visa officer does not have the energy to check your monthly slip. They will only review the materials related to this visa application, so other materials are redundant in their eyes and a waste of their time. Therefore, we should not submit every transaction to avoid counterproductive effects.

In the eyes of most people, when applying for a visa from a developed country like the United States, those with a record of traveling abroad have a higher pass rate than those without a record of traveling abroad.

Yes, applicants with records of traveling abroad have certain advantages in applying for a visa, but this does not mean that they will definitely be able to obtain a visa. For developed countries like the United States, overseas records are only one of the factors they consider.

Although it is difficult to apply for a visa with a white passport, overemphasis on past overseas travel records will also arouse the resentment of the visa officer. Overly complicated overseas travel records will also face the situation of explaining to the visa officer.

Whether it is the application materials you prepare or the answers to questions during the interview, you must be honest and not deceive. Some visa officers are very easy-going. In addition to regular questions during the visa interview, they may also ask some off-topic questions.

For example, he may ask you what you like about this city? After you answer, he may ask if you can give a few examples. If you just answered the previous question casually or deliberately made it up, then the next question will catch you off guard, and your answer may even be full of mistakes.

In addition, some applicants did not actually hear the visa officer’s questions clearly, but were too embarrassed to ask again, resulting in hesitation in answering, or making guesses out of thin air about the questions the visa officer might ask. These are taboos for the visa officer.

There is actually no unified standard for what to wear during the visa interview. As long as it matches your age, it is fine. It does not necessarily have to be formal. If you are a student but dress too professionally, it will look weird in the eyes of the visa officer. At the same time, don’t ignore body language when talking to the visa officer. Our body language can reveal a lot of information to the visa officer.
