Generally immigration petitions and applications for adjustment of status will be denied by the U.S. Citizenship and Immigration Services where there is proof of fraud involved. These immigrants may be accused of fraud and are exposed to possible Green Card annulment though there was no fault of their own. Sometimes, immigration officers obtain uncomplimentary information through a notification by the employer who is sponsoring or with information developed during an applicant’s interview. Hence most marriages based on alleged fraud will be denied at the interview stage and the applicant is placed in deportation proceedings .
The marriage based Green Card interview is conducted by the immigration officers to verify the proof provided with the application. It is usually conducted to find if the applicant's marriage to the US citizen is a legitimate marriage. A legitimate marriage is a marriage that is legally binding and that was not entered into for the purpose of eluding the immigration law. It becomes the sole responsibility of the USCIS to focus on whether the bride and groom intended to establish a life together after their marriage.
In order to find out that a marriage is legitimate for immigration purposes, the examining officer looks into the conduct of the parties after the marriage. Basically, the officers can ask anything under the sun, from your own hobbies to general knowledge of the United States. According to the individuals situation, relevant factors may be addressed at the interview. For example if the green card you have applied for is employment based green card or Work Visa, then interview questions will be related to the work and the nature of work . In cases of marriage based green card, the queries will be relevant to the marriage which include whether the couple is living together and if they have joint property of their own, and whether they have a good relationship between themselves. Hence, any kind of googly questions can be raised by the officers. Things like body language and the presence or absence of a wedding ring are also taken into account. The most important thing to be considered is that, not be nervous and be very honest while answering the questions that are been asked.
It is indeed a tough task to leave your country and migrate to another country and get a visa just like getting US Visa to US. Added to the agony, you answer the immigration officers who are from the country you are going to migrate to as well as to the officers from your own country. Hence it is a lengthy process and supposed to be a stressful period for those who do not follow the rules and regulations. A thorough examination of all relevant information is recommended prior to the preparation and submission of documents to the USCIS.
