EB-2 is an immigrant visa preference category for United States employment-based permanent residency, created by the Immigration Act of 1990. The category includes "members of the professions holding advanced degrees or their equivalent", and "individuals who because of their exceptional ability in the sciences, arts, or business will substantially benefit prospectively the national economy, cultural or educational interests, or welfare of the United States, and whose services in the sciences, arts, professions, or business are sought by an employer in the United States". Applicants (with the exception of applicants applying for an exemption known as National Interest Waiver) must generally have an approved labor certification, a job offer, and their employer must have filed an Immigrant Petition for Alien Worker (Form I-140) with the USCIS.
The statutory requirements may be found in the Immigration and Nationality Act (INA) at Section 203(b)(2). The regulatory requirements may be found in the Title 8 Code of Federal Regulations (8 CFR) at section 204.5(k). There are three sub-categories of EB-2:
Entrepreneurs may also qualify for the EB-2 category under certain conditions.
As of September 2012, the Department of State determined that the FY-2012 numerical limit for the worldwide employment-based preference must be 144,951, and the per-country limit must be 7% of the worldwide cap, regardless of the population of the country. Out of this, the EB-2 category is limited to 28.6% of the worldwide level, plus any numbers not used by the EB-1 category ("spillover").
The Bureau of Consular Affairs has more details about the application process.
EB-2 immigration categories normally require the Labor Certification application, once the employer has obtained the Labor Certification, the employer can file an I-140 immigrant petition for an alien with the USCIS. One purpose of I-140 petition that requires a certified Labor Certification is to establish that the employer has the ability to pay the offered wage stated in the Labor Certification application. The employer must be able to prove its ability to pay the proffered wage at the time the priority date is established, and continuing until the beneficiary employee obtains the lawful permanent residence.
