Foreign nationals without permanent resident status or a work visa are not permitted to work in the United States. An employer seeking to hire a foreign national may file a petition with the United States Department of Homeland Security/ United States Citizenship and Immigration Services (“USCIS”) for an employment visa on behalf of the prospective employee. If the petition is approved, the prospective employee must obtain a “visa stamp” from a United States embassy or consulate (Canadian citizens are exempt from this requirement). To get a temporary U.S. work visa, an employer must file a petition with U.S. Citizenship and Immigration Services (USCIS). An approved petition must be part of the visa request; the types of visas include:
H-1B – for applicants with a college degree hired to do specialised work. The visa is valid for three years and can be extended for an additional three years. The visa is connected to the employer that filed the petition. If there is a change of employer, the new employer must repeat the process. There are 65,000 H-1B visas available each year.
H-1B1 – for applicants with a college degree from Chile and Singapore. The US government grants up to 1,400 visas to Chilean citizens and 5,400 from Singapore each year.
H-2A – for temporary or seasonal agriculture work. It is limited to citizens of qualified countries. Usually valid for up to 1 year and can be extended to a maximum of 3 years.
H-2B – for temporary non-agricultural work. These visas are limited to citizens of qualified countries. Usually valid for up to 1 year and can be extended to a maximum of 3 years.
L – for intercompany transfers (people transferred from a foreign company to a US branch of the company.) The applicant must have been employed at the company for a year before the transfer and work in a managerial level position or higher with specialised knowledge.
0 – for people with extraordinary ability in science, arts, education, business, or athletics.
The standard procedure is to obtain a short-term work visa and then apply for an immigrant visa after the employee has started working in the United States.
For those seeking employment-based immigrant visas:
E-1 – Highest priority employment for those with extraordinary ability in science, arts, education, business, and athletics.
E-2 – for those with advanced degrees or exceptional ability.
E-3 – for skilled workers and professionals, as well as unskilled workers.
E-4 – Members of certain immigrant groups.
E-5 – Immigrant investors in US companies (substantial investment)
Alternatively, an employer may sponsor a potential employee’s application for permanent resident status, referred to as a “green card,” if the employee can establish that the potential employee is a multinational executive/manager transferee, has unique skills, or has been offered a job in the United States. The employer must have been unable to recruit a U.S. worker who meets the position’s minimum requirements.
All employers are obligated to verify that all individuals they employ are authorised to work in the United States.
