C-4 Short-Term Employment Visa: What to Check Before Paid Work in Korea for Up to 90 Days

The C-4 is the status for foreign nationals who will carry out paid activities in Korea for 90 days or less. Even for the same lecture or business trip, whether you receive a fee or service payment in Korea decides whether visa-free entry or a C-3 short-term visit is enough, or whether you need a C-4.

Key points

• The stay is 90 days or less, and extension or change to another work status is generally restricted.

• A contract stating the pay is central to the review, and the visa is usually applied for at a Korean embassy or consulate abroad.

What to prepare and check

Practical cautions

01

Getting paid after visa-free entry

Doing paid work after entering visa-free or on a C-3 is an activity outside your status and can cause problems for both you and the inviting organization.

02

Expecting an extension or change

Switching from C-4 to long-term employment is generally not possible. If long-term work is the goal, consider the E-7 or another suitable status from the start.

03

Extra requirements by activity

Performances need a recommendation letter, advertising models face agency requirements and a consular interview, and camp English teachers must teach at the registered education facility.

Frequently asked questions

Do I need a C-4 for a single guest lecture at a Korean university?

One-off lectures or consultations may be possible under another short-term status. It depends on the fee, frequency and type of invitation, so check in advance.

Is seasonal farm or fishery work a C-4?

Seasonal work is a separate program allocated through local governments and runs as C-4 (short-term) or E-8 (longer-term) depending on the period.

Can I extend beyond 90 days?

Extensions beyond 90 days are generally not allowed and are considered only for unavoidable reasons.
