American immigrants apply for professional immigrants with work permits.

People who intend to become permanent residents of the United States are mostly "eager to move" after having H- 1B status. First, seek the endorsement of the employer, apply for the certification of the Ministry of Labor, and then apply for a permanent residence permit from the Immigration Bureau. This is the only way for most people with H- 1B status, and it is also the only way for most domestic international students to go to the United States. Of course, most people who don't have H- 1B status now have to go this way to get a green card.

The first step is to apply for a labor permit. Work permit is a document that American employers apply to the US Department of Labor for their foreign employees. Under the second priority (EB-2) and the third priority (EB-3) of professional immigration, it is a prerequisite for employers to apply for immigration for foreign employees. Professional immigrants are divided into five categories. The first category gives priority to talents with special skills, outstanding researchers and professors, with an annual quota of about 40 thousand. The second priority is professionals with advanced degrees (master's degree or above), with an annual quota of about 40 thousand; The third category gives priority to skilled workers, professionals (with a bachelor's degree) and other unskilled workers, with 40,000 places per year, of which unskilled workers account for 6,543,800+0,000 places at most; The fourth priority is special immigrants, such as religious people, with an annual quota of about 1 10,000; The fifth priority is investment immigration, and there is also a quota of 1 10,000 every year.

Except for a few people who can omit the application steps of work permit through the National Interest Exemption (NIW) in the second priority of professional immigrants, most of the second priority and third priority applications need to obtain work permits before applying for immigration. Only after the work permit application is approved can the employer submit the immigration application (I- 14o form) for its foreign employees.

Because American immigration law stipulates that when a foreigner applies for ordinary professional immigration, the applicant must not only find a job first, but also prove to the US Department of Labor that no qualified American can or is willing to undertake the job he has found, and this process of proof is called "work permit" application. Many people have a misunderstanding about the work permit, thinking that the work permit is a work permit or a work permit. Actually, a work permit and a work permit are not the same thing at all. Even if the immigrant applicant's work permit is approved, you can't work legally in the United States unless you have other legal work status. The establishment of work permit is only for the protection of American workers' interests by the US Department of Labor, that is to say, under the premise of giving full priority to American workers in the US job market, some jobs that Americans cannot afford or are unwilling to do are left to foreigners and allowed to apply.
