"You don't have papers, so you can't file." "Filing will get you deported." "It's easier if I just pay you directly." Foreign workers hear all three from employers after a workplace injury — and all three are wrong. Korea's Industrial Accident Compensation Insurance (산업재해보상보험, or 산재) covers foreign workers on the same terms as Korean nationals, and in most cases, your visa or documentation status does not disqualify you.

→Workers' Compensation (산재) Applies Regardless of Visa Status

Industrial accident insurance is tied to the employment relationship, not your visa category or immigration status. Courts and the Korea Workers' Compensation and Welfare Service (근로복지공단) have repeatedly confirmed that even undocumented workers can file workers' compensation (산재) claims for workplace injuries. Your employer is legally required to be enrolled in this insurance for virtually all workplaces — even if they never told you, and even if you never saw a premium deducted from your pay.

1What Workers' Compensation (산재) Actually Covers

If you're injured or fall ill because of your work, workers' compensation (산재) can cover medical treatment costs in full, a portion of lost wages during recovery — medical care benefits (요양급여) and temporary disability benefits (휴업급여) — disability benefits if you're left with a permanent impairment, and survivor benefits if a workplace accident is fatal. This applies to sudden accidents — a fall, a machine injury — as well as conditions that developed over time, like repetitive strain injuries or occupational illness, if you can show they're work-related.

2Your Employer Cannot "Handle It Privately" Instead

A common tactic is for an employer to offer cash "under the table" to cover a hospital visit, in exchange for you not filing an official workers' compensation (산재) claim. This almost always shortchanges the worker — it skips proper medical evaluation of the injury's full extent, waives your right to disability benefits if the injury turns out to be worse than it first appeared, and leaves no record if complications arise later. You are not required to accept this arrangement, no matter how the offer is framed.

3Reporting Doesn't Automatically Trigger Deportation

Employers frequently tell undocumented or visa-irregular workers that filing a claim will alert immigration authorities. In practice, workers' compensation (산재) claims are processed by the Korea Workers' Compensation and Welfare Service, a separate body from immigration enforcement, and filing a claim itself is not a routine trigger for a status check. This threat is one of the most common ways employers discourage legitimate claims — don't let it stop you from seeking medical treatment and compensation you're owed.

Your employer being unregistered for insurance, or you being undocumented, does not erase your right to compensation for a workplace injury.

4Report Sub-Contracted and Staffing Agency Injuries Too

Many foreign workers are hired through staffing agencies or labor brokers, especially in construction and manufacturing. If you're injured, you may still be covered even if you're not directly employed by the company where the accident happened — Korean law recognizes shared responsibility in subcontracting chains for industrial accidents. Don't assume you have no claim just because your paycheck comes from a different company than the one where you got hurt.

5There Are Deadlines — Don't Wait

Claims for medical and wage benefits generally must be filed within three years, but evidence gets harder to gather the longer you wait — witnesses move on, employers may alter records, and the causal link between the accident and your condition is easier to establish soon after it happens. Report the incident and seek medical documentation as early as possible, even if you're unsure yet whether you'll file a formal claim.

6A Denied Claim Isn't the End

If the Workers' Compensation and Welfare Service denies your claim — often on the grounds that the injury isn't sufficiently work-related — you can appeal through a formal review process, and ultimately to the courts if necessary. Denials are common on first submission for injuries that developed gradually (like repetitive strain or occupational disease); a well-documented appeal, often with medical opinion support, frequently succeeds where the initial claim did not.

→What to Do Right After a Workplace Injury

  1. Get medical treatment and documentation immediately — the medical record is the foundation of any claim.
  2. Report the accident to your employer in writing if possible, even a text message, to create a timestamped record.
  3. Don't sign anything waiving your rights in exchange for a quick cash payment.
  4. File the workers' compensation (산재) claim yourself or with legal help if your employer refuses to cooperate — you are not dependent on your employer's cooperation to file.

→A Note for Latin American Workers

Workers' compensation systems vary enormously across Latin America, and many clients from Brazil, Mexico, Colombia, and beyond arrive in Korea with very different assumptions about what happens after a workplace injury. I explain your actual rights under Korean law, in Spanish or Portuguese, and help you get medical care and compensation without relying on your employer's version of events.
