Explain in detail how non-immigrant visas in the United States change their status.

Legal visas to enter the United States are divided into immigrant visas and non-immigrant visas. Non-immigrant visas have a certain validity period. Non-immigrant visa holders will lose their legal status if they do not apply for extension or change their status within the validity period. In order to avoid this situation, you must apply for visa extension or change your status.

It is feasible to extend or change non-immigrant status in the United States. However, identity conversion may have an impact on the future. Therefore, it is necessary to keep the consistency between the converted visa and the original visa. For example, it is better to enter the United States with an F- 1 visa than to enter the United States with a B-2 visa and then change to an F- 1 visa.

Although the visa change application can be approved in the United States, it will be difficult for consulates outside the United States to obtain similar visas. And if you want to apply for an immigrant visa in the future, such a record will also bring problems to the parties. Any deception or concealment will become an obstacle to applying for an immigrant visa in the future.

If the person concerned enters the United States to visit relatives with a B-2 visa and finds a job within 30 days, it is deemed that he intentionally conceals his true purpose on the visa. If you find a job within 30-60 days, the previous assumption will not be established, but the Immigration Bureau will still suspect the existence of concealment. If you find a job after 60 days, the immigration department generally does not think that the person concerned has cheated or concealed.

Usually, if a customer successfully changes from a B-2 visa to an H- 1B visa in the United States and intends to re-enter the country with an H- 1B visa after leaving the United States, the visa consul must investigate the authenticity of the customer's original application for a visit visa. For example, if the words to watch the Summer Olympics were on the visa at that time, the personnel concerned must prove that they did watch the Atlanta Olympics, and then they can change their minds.

If the person concerned enters the country with an official visa and then changes to an L- 1 employee transfer visa, this change is reasonable because the work he can do under the L- 1 visa is consistent with the nature of the official visa.

Those who have already applied for a green card will be more troublesome if they apply for a visitor visa or a student visa at the US consulate, but it will not affect if they apply for an H- 1B visa, because the law allows the parties to have dual purposes. This means that the parties can continue to have the idea of staying in the United States temporarily during the green card application period.

However, the American consul can still be cautious about the parties. Even if the dual purpose is not a problem, the American consul can still question the purpose of applying for a visit visa or the authenticity of the work.

There is a client whose B- 1 visa expired a few weeks ago, but he has been in the United States for six months and recently wants to find a job. Just as he was leaving America, he got a job opportunity. In this case, it is impossible for him to change his status in the United States because his visa has expired. There is a similar situation, the customer is H- 1B in the United States, and later gave up his job or was terminated by his employer. The client soon lost his identity. If a customer gets another job a few months later, but has to leave the country because he lost his original identity, he can apply for a new H- 1B visa to legally enter the United States through the consulate outside the United States.
