International students in South Korea holding D-2 or D-4 visas can legally work part-time after securing approval from both their university and the Korean Immigration Office. The work hour limits depend on visa types, academic levels and proven Korean (TOPIK) or English language proficiency test scores. 

The D-2 Visa is designed for international students enrolled in full-time degree programs at South Korean universities. This includes Associate, Bachelor’s, Master’s, and PhD students. While these students can apply for a part-time work permit immediately upon arrival, the actual hours they are allowed to work depend on their academic level and language proficiency.

For students meeting standard requirements, weekday working hours are capped to ensure studies remain the top priority. However, weekends and official semester vacations offer relaxed limits to help students earn more.

South Korea rewards high academic performance and strong language skills. If you demonstrate excellent grades (usually maintaining a GPA above 2.0 or a ‘C’ average) and certified language fluency, the Immigration Office may grant extended weekday work privileges.

To protect international students and ensure smooth communication at workplaces, South Korea enforces strict language proficiency benchmarks. Failing to meet these standards limits legal working time to just 10 to 15 hours per week.

Korean Language Requirement (TOPIK)

For general programs, students must hit one of the following milestones to unlock full part-time work privileges:

• TOPIK Certificate: Achieve TOPIK Level 3 or higher.

• Language Program: Successfully complete Level 3 or higher at a recognized Korean language institute or pass corresponding levels of the Korea Immigration and Integration Program (KIIP).

The D-4-1 visa is granted to students attending regular Korean language study programs at university-affiliated institutes. The work path for language trainees is split into two strict phases.

The First 6 Months: Zero Work Allowance

During your first 6 months of living in South Korea on a D-4-1 visa, part-time work is strictly prohibited. This rule is absolute, meaning you cannot take on any job during this initial training period. You must bring enough personal funds to cover your accommodation and food costs for the first half of the year.

After 6 Months: Permitted Work Hours Matrix

Once you complete 6 consecutive months of legal residency, maintain an attendance rate of 90% or above, and receive your school’s endorsement, you can apply for a part-time permit. The allowable hours are directly linked to your TOPIK or KIIP levels:

Working without a legal stamp is a serious offense in South Korea. Follow this step-by-step process to secure your part-time work permit before your first shift:

• Secure a Job Offer: Find an employer willing to hire you and sign a Standard Labor Contract detailing hours, location, and the current national minimum wage.

• Get University Approval: Take the contract and the “Part-Time Work Confirmation Form” to your university’s international student office to get their official signature and seal.

• Prepare Document Packet: Gather your Passport, Alien Registration Card (ARC), Enrollment Certificate, Transcript (GPA proof), Language Test Scores, and the Employer’s Business Registration Copy.

• Submit to Immigration: Upload your files online via the official HiKorea portal or make an appointment at your local Immigration Office.

• Wait for Approval: Wait for the official approval stamp before starting your physical work. Working during the application processing period is considered illegal.
