Assessing U.S. Foreign Investment Risk Amid Trump's Immigration-Driven Law Enforcement Surges

The Trump administration’s aggressive immigration enforcement and protectionist trade policies have created a volatile environment for foreign direct investment (FDI), particularly in U.S.-South Korea manufacturing partnerships. These policies, rooted in the “America First” doctrine, have introduced dual risks: labor market disruptions from immigration raids and economic uncertainty from tariff-driven trade tensions. For investors, the interplay between these factors raises critical questions about the resilience of cross-border supply chains and the geopolitical trust underpinning U.S.-Korea economic cooperation.

Immigration Enforcement and Labor Market Volatility

The Trump administration’s focus on immigration enforcement has escalated dramatically in 2025, with ICE audits targeting industries reliant on immigrant labor. A landmark example is the September 2025 raid on a Hyundai-LG battery plant in Georgia, where 475 workers—most South Korean nationals—were detained. This operation, described as the largest single-site immigration enforcement action in U.S. history, halted production at a facility central to Hyundai’s $4.3 billion investment in U.S. electric vehicle (EV) manufacturing [1][2]. South Korea’s government expressed “concern and regret,” emphasizing that such actions risk undermining trust in the U.S. as a stable partner for foreign investment [3].

According to a report by Reuters, the raid disrupted not only Hyundai’s operations but also broader U.S.-South Korea collaboration in clean energy sectors. South Korean firms, already navigating Trump’s 25% tariffs on steel and aluminum imports [4], now face heightened compliance costs and workforce instability. Data from the Corporate Compliance Insights indicates that 70% of U.S. employers anticipate significant operational impacts from increased immigration enforcement, with manufacturing and agriculture sectors most vulnerable [4]. For South Korean companies, the combination of labor shortages and regulatory unpredictability complicates long-term planning, deterring capital-intensive investments in U.S. markets.

Tariff Policies and Supply Chain Reconfiguration

Parallel to immigration enforcement, Trump’s tariff policies have reshaped U.S.-South Korea trade dynamics. The administration’s reciprocal tariff framework, which ties trade balances to national security and immigration compliance, has imposed 25-40% tariffs on South Korean exports, including semiconductors and automotive parts [2]. A report by the Korea International Trade Association highlights that these tariffs have forced South Korean firms to accelerate supply chain diversification, with some shifting production to Vietnam and India to mitigate risks [5].

The geopolitical implications are profound. South Korea, a key U.S. ally in the Indo-Pacific, now faces a dilemma: aligning with U.S. strategic priorities while safeguarding its economic interests in China. As stated by the Carnegie Endowment for International Peace, South Korea’s advanced manufacturing capabilities have become a focal point in U.S. efforts to counter Chinese influence, yet Trump’s transactional approach—exemplified by demands for increased military cost-sharing and retaliatory tariffs—has eroded confidence in bilateral stability [1].

Geopolitical Trust and Investment Implications

The Hyundai-LG raid underscores how domestic policy shifts can directly strain international partnerships. South Korea’s public response, which included dispatching officials to the raid site to advocate for detained workers, signals growing unease over U.S. enforcement practices [3]. For investors, this incident highlights the vulnerability of FDI to geopolitical miscalculations. A JPMorgan analysis notes that Trump’s “America First” policies have created a dual-track system: fast-tracking investments from allied nations while scrutinizing those from adversarial countries [4]. However, the confluence of immigration raids and tariffs has muddied this framework, making the U.S. an increasingly unpredictable destination for South Korean capital.

Strategic Adjustments and Investor Considerations

South Korean firms are adapting to these challenges through supply chain resilience strategies. For instance, Samsung and SK Hynix have expanded chip manufacturing in Texas and Arizona but are simultaneously investing in Southeast Asia to hedge against U.S. policy risks [5]. Investors must weigh these adjustments against broader trends: while U.S. incentives for EV and semiconductor production remain attractive, the compounding risks of labor disruptions and tariff volatility necessitate contingency planning.

Conclusion

Trump’s immigration-driven law enforcement surges and protectionist trade policies have created a high-risk environment for U.S.-South Korea manufacturing partnerships. The Hyundai-LG raid exemplifies how domestic enforcement can directly disrupt global supply chains and erode diplomatic trust. For investors, the lesson is clear: diversification and geopolitical agility are now non-negotiable. While the U.S. remains a critical market, the interplay of immigration enforcement and tariff policies demands a recalibration of risk assessments and long-term strategies.
