Historical Foundation Methodology

Historical Foundation

The U.S. immigrant labor landscape is a constantly evolving entity, influenced by a range of policy decisions, global events, and economic factors. Its intricate relationship with broader domestic and international dynamics makes it a critical area of focus for a range of stakeholders.

The Immigration and Nationality Act (INA) forms the bedrock of U.S. immigration policy, defining categories like refugees and asylees based on persecution fears. These groups, alongside other visa holders, contribute to the U.S. labor market. The system has been subject to fluctuations due to political changes, most noticeably during the Trump administration, which tightened visa issuances and refugee admissions.

Disruptions and Recovery

The COVID-19 pandemic added another layer of complexity. Visas dropped sharply during the pandemic but have nearly doubled since. This shows that the U.S. is still attractive for immigrants looking for work. However, not every type of visa has bounced back. For example, fewer tourist and business visas are being given out than before the pandemic, affecting industries that depend on these visitors.

Labor Categories

H1B Visas Highly skilled professionals in fields like IT, engineering, and healthcare. These visas are in high demand and reach their limit quickly.
H2A Visas Primarily used for temporary or seasonal agricultural work. These visas were not restricted during the pandemic, highlighting their essential status.
B1/B2 Visas Though not strictly labor visas, these affect sectors reliant on tourism and international business.
F1 Visas Allow international students to study in the U.S. and sometimes work part-time.
J1 Visas Used for cultural and educational exchange programs, including work-study.
H Visas Includes other types of work-related visas not falling under the specialized labor category.

Geographical Shifts

Country-based contributions to the U.S. immigrant labor pool have seen shifts, too. While Mexico's share of both immigrant and nonimmigrant visas has increased post-pandemic, China's has decreased. Regional trends also indicate that visas issued to Asian nationals have decreased, while those to North American nationals have increased.

Backlogs and Policy Effects

The system isn't without its challenges. A considerable backlog exists in asylum hearings, affecting the labor force's makeup in sectors that often employ asylees. Policy shifts from the Trump to the Biden administration have influenced both the volume and the source countries of incoming immigrant labor, which could have longer-term implications on various U.S. industries.

Methodology

An Overview of Our Approach

Our methodology leverages the OON framework to shape U.S. immigration policy, with a particular emphasis on identifying high-demand roles suitable for immigrant workers. The OON considers four key variables:

Occupational Complementarity:
This metric evaluates how seamlessly an occupation integrates into the existing U.S. labor market. It identifies roles that are not just crucial to the economy but also elevate productivity across sectors. An occupation's complementarity index, which ranges from zero to one, is calculated by averaging its pairwise complementarity values with other roles. Occupations are considered complementary if their industry employment shares co-vary.

Occupational Opportunity Network:
The network diagram identifies strategic occupations that will be in high demand for the next decade; are historically immigrant intensive; and have a high degree of complementarity with other occupations. In the network each node represents an occupation. The distance between the nodes reflects the pairwise complementarity detailed above.

Projected Visa Demand:
This metric which can help prioritize occupations likely to require workers with visas is given by the projected employment change in the occupation plus projected labor market exits from the occupation (an estimate of the number of workers expected to exit the labor force due to retirement or other factors) all multiplied by the share of people currently working in the occupation on a visa.

Immigrant Intensity:
This metric gauges the presence of foreign-born workers in various occupations, using a 17% national average for comparison. It helps us identify sectors already benefiting from or potentially conducive to immigrant labor.

Training Required:
This variable sorts occupations based on their training prerequisites as classified by O*NET Job Zones. This enables us to pinpoint roles that are both vital to the U.S. economy and accessible to immigrants, given their educational and vocational backgrounds.

Our methodology integrates these key variables for a holistic understanding of the U.S. labor market. This unified approach helps us grasp how immigrant labor enhances current workforce structures and pinpoints areas where tailored immigration policies can address labor shortages effectively.
