Generally, a citizen of a foreign country who wishes to enter the United States must first obtain a visa, either a nonimmigrant visa for a temporary stay, or an immigrant visa for permanent residence. Visitor visas are nonimmigrant visas for persons who want to enter the United States temporarily for business (visa category B-1), for tourism (visa category B-2), or for a combination of both purposes (B-1/B-2).
F1 is for individuals who wish to study in the US whereas F2 is for their dependents who accompany them and live with them in the US. F1 holders have full time status and various work options whereas the F2 holders have restrictions on the full time study and employment options in the US.
The H-1B program applies to employers seeking to hire nonimmigrant aliens as workers in specialty occupations or as fashion models of distinguished merit and ability. A specialty occupation is one that requires the application of a body of highly specialized knowledge and the attainment of at least a bachelor’s degree or its equivalent. The intent of the H-1B provisions is to help employers who cannot otherwise obtain needed business skills and abilities from the U.S. workforce by authorizing the temporary employment of qualified individuals who are not otherwise authorized to work in the United States.
The law establishes certain standards in order to protect similarly employed U.S. workers from being adversely affected by the employment of the nonimmigrant workers, as well as to protect the H-1B nonimmigrant workers. Employers must attest to the Department of Labor that they will pay wages to the H-1B nonimmigrant workers that are at least equal to the actual wage paid by the employer to other workers with similar experience and qualifications for the job in question, or the prevailing wage for the occupation in the area of intended employment – whichever is greater.
The L-1B nonimmigrant classification enables a U.S. employer to transfer a professional employee with specialized knowledge relating to the organization’s interests from one of its affiliated foreign offices to one of its offices in the United States. This classification also enables a foreign company that does not yet have an affiliated U.S. office to send a specialized knowledge employee to the United States to help establish one.
The Exchange Visitor (J) non-immigrant visa category is for individuals approved to participate in work-and study-based exchange visitor programs. Participants are integral to the success of the program. Here you can learn more about obtaining the J-1 Visa and other relevant visas.
Every fiscal year (October 1st – September 30th), approximately 140,000 employment-based immigrant visas are made available to qualified applicants under the provisions of U.S. immigration law. Employment based immigrant visas are divided into five preference categories. Certain spouses and children may accompany or follow-to-join employment-based immigrants.
A Fourth Preference applicant must be the beneficiary of an approved Petition for Amerasian, Widow(er), or Special Immigrant, with the exception of Certain Employees or Former Employees of the U.S. Government Abroad (see number 3 below). Labor certification is not required for any of the Certain Special Immigrants subgroups. Special Immigrants receive 7.1 percent of the yearly worldwide limit of employment-based immigrant visas.
