Korea C-4 Short-term Employment — Seasonal Work and Short-term Assignments

Overview

C-4 (Short-term Employment) covers paid work of up to 90 days, split between seasonal work (C-4-1 to 4) and other short-term employment (C-4-5).

Seasonal work covers cultivation and harvesting of crops (including linked primary processing) and primary processing of marine products; C-4-5 covers one-off performances, advertising and fashion modelling, lectures, research, technical guidance and similar profit-oriented short-term work.

Requirements, documents and periods in this article follow the Korea Immigration Service (Ministry of Justice) Foreign Residence Guide Manual (March 2026) and the Immigration Act and its Enforcement Decree/Rules (law.go.kr). The manual is supplementary guidance; approval is decided by the reviewing officer. Always confirm your own case with the competent Immigration Office.

  • Employment in crop cultivation and harvesting (including linked primary processing) and primary processing of marine products, as determined by the Minister of Justice in consultation with the competent ministries (C-4-1 to 4)
  • Profit-oriented short-term employment such as one-off performances, advertising and fashion modelling, lectures, research and technical guidance (C-4-5)

  • Employer confirmation for seasonal worker placement (issued by the local government)

Application Process

  1. Check eligibility — confirm your current status, career, degree and contract type match the requirements.
  2. Prepare documents — foreign public documents need a translator's certification plus an apostille (or consular confirmation for non-member states).
  3. Book a visit — reserve a slot at your Immigration Office via HiKorea (www.hikorea.go.kr), or file online where e-Application is available.
  4. File and pay — submit the Integrated Application Form (Form No. 34) and pay the screening fee.
  5. Review — respond to any request for supplementary documents within the deadline.
  6. Result — on approval, the period of stay and status are granted; reissue your ARC if required.

Key Points

  • Seasonal work (C-4-1 to 4) does not allow adding a workplace, and a local government officer must accompany any workplace change.
  • Grounds for changing seasonal workplace: (1) the employer breached conditions and failed to remedy them; (2) work cannot continue for reasons not attributable to the worker; (3) it is socially unreasonable to continue at the original employer's site. The former employer must file a change-of-employment report with Immigration and the local government.
  • Authority to permit workplace change/addition for C-4-5 is delegated to the head of the local Immigration Office, and no ministerial employment recommendation is needed for a change (except in sectors within E-1 to E-7 where a recommendation is mandatory).
  • Changing the venue of an E-6-1 performance at the agency's direction needs no separate permit or report, but E-6-2 activity requires the employer to file a change report.
  • Documents issued in Korea must normally be dated within 3 months unless another validity period applies.
  • Documents already on file in your alien registration record need not be resubmitted.
  • Health certificates, drug test results and pre-employment medical reports must be submitted sealed by the issuing hospital (do not open).
  • You must be in Korea when applying; leaving the country after filing may result in refusal.
  • Screening fees are non-refundable once the application is accepted.
  • The head of the Immigration Office may add or waive documents where necessary for review.
