A Growing Divide in South Korea’s Classrooms
South Korea has aggressively positioned itself as a premier destination for international education, leveraging the global popularity of its pop culture and expanding academic programs. However, this rapid expansion has collided with a significant policy failure. A recent study reveals that more than 1 in 9 international students in the country became unauthorized residents in 2024 by overstaying their visas or working beyond permitted levels. This statistic highlights a widening gap between the government’s recruitment goals and the reality of integration for foreign students.
The country has shifted dramatically from being a sender of students to the United States and Europe to becoming a major receiver. Two decades ago, the nation sent many of its brightest minds abroad. Today, it attracts students from around the world, with numbers rising from a modest 17,000 in 2004 to approximately 226,000 in 2023. This growth accounts for 7.5 percent of the total higher education student population in South Korea. Yet, as these numbers swell, the systems designed to manage the students and transition them into the workforce are struggling to keep pace.
The findings come from a report by Kim Gyu-chan, an associate professor at Gangneung-Wonju National University. Utilizing data from the Ministry of Justice obtained through a Freedom of Information request, the study paints a picture of a system where quantitative growth has outstripped the capacity for sustainable integration. The core issue lies in a systemic disconnect between education, employment opportunities, and long-term residency pathways.
Professor Kim argues that the current framework treats international students as temporary fillers for the labor market rather than as potential long-term residents. This perception inevitably leads to a rise in undocumented cases as students find themselves with limited legal options to remain in the country after completing their studies.
This suggests that while the overall number of foreign students has grown, the stability and legality of their stays have declined.
Soaring Numbers and Visa Violations
The scale of unauthorized residence among foreign students has reached alarming levels. According to the report, 34,267 people who originally entered Korea to study at universities or language institutes overstayed their visas or worked without permission in 2024. This figure represents a more than fivefold increase from the 6,782 cases recorded in 2014. While the total number of international students has increased over this decade, the rate of visa violations has also climbed, indicating a deterioration in the quality of stay management.
Data shows that 9,580 of the unauthorized residents had previously held D-2 student visas for degree programs, while 24,687 had held D-4 visas for language training. The proportion of foreign students violating visa terms rose from 7.8 percent in 2014 to a peak of 15.7 percent in 2022. Although this rate dipped slightly to 11.6 percent in 2023 and 2024, it remains well above the levels seen in the mid-2010s.
The prevalence of violations among D-4 visa holders is particularly concerning. These students arrive for non-credit-bearing courses, primarily Korean language studies, which constitute the largest share of international enrollments at 33 percent. Language trainees appear to face greater risks of lapsing into illegal immigration status, either unintentionally or deliberately, compared to those enrolled in degree programs. This trend raises concerns that the rapid expansion of language programs could exacerbate problems if structural issues in recruitment and support remain unaddressed.
The Dominance of Vietnamese Nationals
The study uncovered a striking demographic trend regarding unauthorized residency. By nationality, Vietnamese students accounted for the overwhelming majority of those overstaying visas or working without proper permission. Among those on D-2 academic visas, 69.7 percent of the violators were from Vietnam. This was followed by Uzbekistan at 13 percent, Mongolia at 6.9 percent and China at 3.4 percent.
The concentration is even more pronounced among D-4 language trainee visa holders, where 88.9 percent of the unauthorized residents were Vietnamese nationals. This marks a dramatic shift over the last decade. The share of unauthorized Vietnamese students among former D-2 visa holders surged from 1.51 percent in 2014 to 69.7 percent in 2024. Similarly, the proportion among former D-4 visa holders jumped from 13.4 percent to 88.9 percent during the same period.
This data suggests that the challenges facing Vietnamese students are specific and acute. While South Korea actively recruits from Vietnam to bolster its student numbers, the support structures and legal pathways for these students may be insufficient. The financial pressure on language trainees, who often cannot work as many hours as degree students or who face higher tuition costs without scholarship support, likely contributes to this disparity.
Systemic Barriers to Legal Residency
One of the primary drivers of this crisis is the unrealistic visa system that governs the transition from student to worker. The research highlights a paradox in the D-10 job-seeking visa and the E-7 professional worker visa. The government allows D-10 holders to extend their stay to look for work, but strict limits on economic activity during this period often leave graduates in financial distress. Without the ability to work legally to support themselves while job hunting, many turn to unauthorized employment.
Furthermore, the E-7 visa requirements for skilled foreign professionals present significant obstacles. The visa mandates minimum wage thresholds that often exceed the average pay offered by small and medium-sized enterprises. These salary requirements pose a major barrier for liberal arts graduates, who may find job opportunities in smaller firms that cannot meet the government’s salary standards for visa sponsorship.
Kim Gyu-chan explained that the core process of settling requires obtaining a skilled workforce visa, ranging from E-1 to E-7. This process requires students to find a job connected to their field of study, obtain a certain salary, and ensure their employers hold specific qualifications.
Realistically, this makes it difficult for humanities or social science majors to obtain, while acting as an obstacle for those wanting to work at small and medium-sized businesses.
These structural hurdles frequently push students into the shadows, forcing them to work without proper visas simply to make ends meet. The desire to stay and contribute to the economy clashes with regulatory frameworks that do not account for the realities of the labor market.
The Burden on Educational Institutions
The government’s response to these challenges has placed an undue burden on academic institutions. The International Education Quality Assurance System has come under fire for shifting the responsibility of immigration control onto universities. This system uses illegal stay rates as a key metric for university accreditation.
By tying accreditation to the behavior of students regarding visa compliance, the government has effectively turned educators into gatekeepers. Universities must focus heavily on monitoring students for potential illegal employment rather than providing quality education or robust career support. This approach detracts from the primary mission of educational institutions and creates an adversarial relationship between schools and their international students.
Professor Kim criticized this approach, arguing that international students should not be viewed as administrative burdens or temporary substitutes for the declining school-age population. Instead, he insists they must be recognized as future residents and valuable human resources. The current quality assurance system, however, incentivizes universities to either restrict enrollment from higher-risk demographics or invest resources in policing students rather than educating them.
Aligning Policy with Reality
The findings arrive at a critical moment for South Korean policy. The education ministry’s Study Korea 300K initiative, announced in 2023, aims to attract 300,000 international students by the end of 2027. Concurrently, the justice ministry’s 4th Basic Plan for Immigration Policy designates international students as potential skilled workers to be retained in the labor market.
Despite these high-level goals, the gap between policy ambitions and on-the-ground reality remains wide. The study suggests that regulatory bottlenecks are actively undermining the government’s talent retention strategy. Without structural changes, expanding student numbers alone will not translate into successful settlement or talent retention.
Kim urged the government to follow examples from countries such as Germany and Japan. Both nations have integrated international student policy into broader national talent and immigration strategies. To achieve a similar integration, Kim proposed creating a unified digital platform. This platform would link data from the justice and education ministries and universities in real-time. Tracking graduates’ career paths through such a system would allow policymakers to adjust regulations and improve policy effectiveness based on actual outcomes.
Additional recommendations include creating career support centers dedicated specifically to international students and offering incentives to universities that partner successfully with local businesses to hire graduates. These steps would enhance employment prospects and help stabilize postgraduation settlement. By treating students as long-term human capital rather than temporary stopgaps, South Korea can begin to close the gap between its recruitment targets and its integration capabilities.
