President Donald Trump’s push to revitalize American manufacturing by luring foreign investment into the U.S. has run headlong into one of his other priorities: cracking down on illegal immigration. Hardly a week after immigration authorities raided a sprawling Hyundai battery plant in Georgia and detained more than 300 South Korean workers, South Korean President Lee Jae Myung warned that the country’s companies may be reluctant to take up Trump’s invitation to invest in the United States. If the U.S. cannot issue visas promptly to the technicians and skilled workers needed to launch plants, Lee indicated that establishing a local factory in the U.S. would become increasingly difficult. The raid underscores a conflict between the Trump administration’s mass deportation goals and its effort to attract foreign investment to bolster the U.S. economy and create jobs.

Trump’s economic strategy includes heavy tariffs on imports, pressing foreign companies to produce locally to avoid high fees. South Korea has pledged $350 billion in investments to the U.S. following a trade deal announced in July. However, the recent crackdown jeopardizes this investment initiative. Experts have described the raid as a strategic misstep, complicating the established practice of foreign companies sending specialists to train U.S. workers often in a supportive role. Immigration experts are particularly perplexed, noting that such raids could deter foreign investment, conflicting with the more business-friendly environment Trump seeks to promote.

While immigration officials maintain that those detained were unlawfully working, many were reportedly operating under visa provisions. Discussions between South Korean and U.S. officials may lead to a new visa category aimed at easing the process for South Korean workers. Experts argue that without significant reform to the U.S. visa system, attracting foreign investment and skilled labor will remain a challenge.
