The First Steps toward an Immigrant Visa: Labor Certification and Filing a Petition To be considered for an immigrant visa under some employment-based categories below, the applicant's prospective employer or agent must first obtain a labor certification approval from the Department of Labor. Once received (if required), the employer then files an Immigrant Petition for Alien Worker, Form I-140, with the U.S. Citizenship and Immigration Services (USCIS) for the appropriate employment-based preference category. (NOTE: Persons with extraordinary abilities in the Employment First preference category are able to file their own petitions.) When filing the Immigrant Petition for Alien Worker, Form I-140, see the detailed form instructions, as well as more detailed requirement's information on the USCIS Permanent Workers webpage.

CATEGORIES

Employment First Preference (E1): Priority Worker and Persons of Extraordinary Ability

There are three sub-groups within this category:

1. Persons with extraordinary ability in the sciences, arts, education, business, or athletics. Applicants in this category must have extensive documentation showing sustained national or international acclaim and recognition in their fields of expertise. Such applicants do not have to have specific job offers, so long as they are entering the U.S. to continue work in the fields in which they have extraordinary ability. Such applicants can file their own Immigrant Petitions for Alien Worker, Form I-140, with the USCIS.
2. Outstanding professors and researchers with at least three years experience in teaching or research, who are recognized internationally. Applicants in this category must be coming to the U.S. to pursue tenure, tenure track teaching, or a comparable research position at a university or other institution of higher education. The prospective employer must provide a job offer and file an Immigrant Petition for Alien Worker, Form I-140, with the USCIS.
3. Multinational managers or executives who have been employed for at least one of the three preceding years by the overseas affiliate, parent, subsidiary, or branch of the U.S. employer. The applicant’s employment outside the U.S. must have been in a managerial or executive capacity, and the applicant must be coming to work in a managerial or executive capacity. The prospective employer must provide a job offer and file an Immigrant Petition for Alien Worker, Form I-140, with the USCIS.

Employment Second Preference (E2): Professionals Holding Advanced Degrees and Persons of Exceptional Ability

A Second Preference applicant must generally have a labor certification approved by the Department of Labor. A job offer is required and the U.S. employer must file an Immigrant Petition for Alien Worker, Form I-140, on behalf of the applicant. Applicants may apply for an exemption, known as a National Interest Waiver, from the job offer and labor certification if the exemption would be in the national interest. In this case, the applicant may self-petition by filing the Immigrant Petition for Alien Worker, Form I-140, along with evidence of the national interest. Professionals Holding Advanced Degrees and Persons of Exceptional Ability receive 28.6 percent of the yearly worldwide limit of employment-based immigrant visas, plus any unused visas from the Employment First Preference category.

There are two subgroups within this category:

1. Professionals holding an advanced degree (beyond a baccalaureate degree), or a baccalaureate degree and at least five years progressive experience in the profession.
2. Persons with exceptional ability in the sciences, arts, or business. Exceptional ability means having a degree of expertise significantly above that ordinarily encountered in the sciences, arts, or business.

Employment Third Preference (E3): Skilled Workers, Professionals, and Unskilled Workers (Other Workers)

A Third Preference applicant must have an approved Immigrant Petition for Alien Worker, Form I-140, filed by the prospective employer. All such workers generally require labor certification approved by the Department of Labor. Skilled Workers, Professionals, and Unskilled Workers (Other Workers) receive 28.6 percent of the yearly worldwide limit of employment-based immigrant visas, plus any unused visas from the Employment First Preference and Second Preference categories.

There are three subgroups within this category:

1. Skilled workers are persons whose jobs require a minimum of 2 years training or work experience that are not temporary or seasonal.
2. Professionals are members of the professions whose jobs require at least a baccalaureate degree from a U.S. university or college or its foreign equivalent degree.
3. Unskilled workers (Other workers) are persons capable of filling positions that require less than two years training or experience that are not temporary or seasonal.

Employment Fourth Preference (E4): Certain Special Immigrants

A Fourth Preference applicant must be the beneficiary of an approved Petition for Amerasian, Widow(er), or Special Immigrant, Form I-360, except 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.
