H1B visa is the most important type of work visa in the United States. It is a non-immigrant visa granted to foreign skilled workers employed by American companies. H1B visa holders can stay in the United States for three years, and then they can extend their stay for another three years. At the end of the six-year period, they must leave the United States if their status has not been changed.

H1b visa is relatively tedious in material preparation. Many people choose to apply for it through H1b lawyer(also known as h1b律师), because the lawyer fee(also known as h1b律师费) of H1b is not high and most people can afford it. After entrusting a lawyer, it will be much easier for people to prepare for h1b application and rfe without affecting their work and life. However, some applicants will handle it by themselves. In addition to the usual updates on the official website of the immigration bureau, they can also read more h1b articles(also known as h1b文章), which will provide many points for attentions.

However, there is a lottery for h1b visa. Many people fail in the lottery because it is a computer lottery, which is random and there is no way to prepare and control it. Therefore, you can also try to get a green card, the U.S. permanent resident card, also known as the green card, which is used to prove that a foreigner has permanent resident status in the United States. Legal permanent residency for green-card holders is an officially granted immigration benefit that includes a conditional permit to reside and work in the United States. The holder must maintain his permanent resident status and may lose it if one of the conditions for that status is no longer met.

However, the green card is not so easy to apply for, the requirements are relatively high, the green card schedule(also known as 绿卡排期) is also very long, so you can choose to find immigration lawyers(also known as 移民律师) to help apply for.
