U.S. Immigration Policy, NAFTA, and Foreign Workers: An Analysis

Citizenship Preferences and Employment Fairness

Characterizations such as "fair" or "unfair" are value judgments — by definition, they cannot be facts. The question of whether it is an unfair employment practice for an employer to prefer a U.S. citizen is therefore a normative one. Any preference not rooted in empirical analysis is, in that sense, unfair — only hard empirical facts are neutral. Employer preferences based on citizenship alone lack such an empirical foundation and thus cannot be defended as objectively fair.

Title VII and the Legality of National-Origin Discrimination

Beyond the question of fairness, it is not actually legal to discriminate on the basis of national origin. Title VII of the Civil Rights Act of 1964 prohibits such discrimination for covered employers. Accordingly, a policy of preferring U.S. citizens over equally qualified foreign nationals who are legally authorized to work in the United States would be both unfair and illegal. A covered company is obligated to hire the best candidate who is legally permitted to work in the country, regardless of citizenship status.

As to whether non-discrimination in hiring is a wise policy, the answer depends on one's perspective. Title VII was written primarily as a social policy, though it directly affects employment. As a measure for eliminating discrimination in the workplace, it functions well. At the same time, employment policies serve multiple government objectives. In the context of foreign workers specifically, the non-discrimination rule is intended to expand and improve the pool of labor available to American corporations. On that score, the policy is arguably effective: it creates more opportunities for the United States to attract top global talent by giving high-quality foreign workers a better chance of being hired. If the objective is also to improve the overall immigrant pool, the policy serves that goal as well. While it contrasts with the family-reunification focus of other immigration policy streams, the non-discrimination rule does create a pathway for companies to recruit skilled immigrants for positions in the U.S.

NAFTA, TN Workers, and Regional Labor Mobility

The claim that TN visa workers from Canada or Mexico can work in the United States more easily than workers from other countries is well founded. This arrangement makes sense, particularly in light of the North American Free Trade Agreement (NAFTA). Politically, Canada and Mexico are the two countries with which the United States maintains its closest ties — they are immediate neighbors, which strengthens the case for preferential labor arrangements. Proximity also makes it more likely that skilled workers from those countries will be willing to relocate to the U.S.

Economically, there are two ways to assess this preference. First, NAFTA already facilitates relatively smooth movement of goods and capital among the three countries, so extending that ease to the movement of labor is a logical complement. Some would argue that NAFTA does not go far enough in this regard compared to frameworks like the European Union's single market. However, a second view holds that any geographic preference introduces economic inefficiency. If the United States were to set an annual immigration quota — say, 500,000 workers — the economically optimal approach would be to select the 500,000 most qualified individuals from the entire global pool. Favoring one country over another acts as a barrier to this ideal outcome and generates deadweight loss.
