An E-2 teaching visa requires more than a degree and a contract. Korea also requires a health check and a criminal record check, and applicants consistently underestimate the first because it looks administrative. It is not purely administrative.
→Two Separate Checks, Often Confused
| Medical check (채용신체검사) | Criminal record check | |
|---|---|---|
| Where | A designated hospital in Korea, or as required abroad | Your home country, then apostilled |
| What it covers | General health plus a drug screen | Convictions and, depending on the country, other dispositions |
| When it bites | At issuance and often again at extension or workplace change | Mostly at first issuance |
Applicants prepare carefully for the second and treat the first as a formality. The pattern of problems runs the other way.
1The Drug Screen Is the Part That Matters
The health check for this category includes screening for narcotics. Nobody hides this, but it is easy to miss inside a general medical form, and many teachers only register it when a result comes back flagged.
Two situations account for most problems. The first is legitimate prescribed medication that produces a reading. The second is something consumed abroad that was lawful where it happened.
That second point deserves emphasis. Cannabis is legal in several countries that send teachers to Korea. Korean law can reach a Korean national's conduct abroad, and separately, a positive screen at a Korean hospital creates a present fact inside Korea that will be dealt with under Korean rules. "It was legal where I did it" is not the shield people assume.
The screen does not ask where you were. It asks what is in the sample.
2Prescribed Medication: Disclose Before, Not After
If you take medication that could affect a screen — certain treatments for attention disorders, some pain medication, some psychiatric prescriptions — bring documentation to the appointment rather than waiting to be asked.
A prescription presented at the time is a routine explanation. The same prescription produced after a flagged result is an explanation that arrives late, and lateness itself becomes part of the picture.
Where the medication was prescribed abroad, an English record naming the drug and the prescriber is worth carrying. Reconstructing it later from another country is slow.
3Timing Is Tighter Than People Expect
Results are not instant, and the check has to be current for the application it supports. Teachers arriving to start a semester routinely find that the sequence — hospital, results, submission, processing — does not fit the days available before classes begin.
The check also reappears later. A workplace change or an extension can require a fresh one, which surprises teachers who assumed it was a one-time hurdle at entry.
4What an Abnormal Result Actually Triggers
Three things can follow, and they run in parallel rather than in sequence.
The immigration consequence is the most immediate: the visa is not issued, or an existing status comes under review. The employment consequence usually arrives fastest, because a school cannot place a teacher whose status is unresolved. And a narcotics finding can bring a criminal investigation, which is an entirely separate track with its own procedure and its own timeline.
People tend to focus on the visa and are caught off guard by the third. If a screen produces a narcotics result, treat it as a criminal matter first — what you say in the days that follow matters more than the visa paperwork.
5Health Findings Other Than Drugs
Most other findings are handled, not fatal. A condition that is treated and documented is generally a matter of paperwork rather than refusal. What causes difficulty is a gap between what was declared and what the check shows.
Declare accurately. An inconsistency is a much worse problem than the underlying condition almost ever is.
→Before the Appointment
- Confirm with the employer exactly which check is required and where — requirements differ by category and by whether you apply inside or outside Korea.
- Bring documentation for any medication — before the sample, not after the result.
- Leave more time than the school suggests — results plus processing rarely fit a tight arrival schedule.
- Do not assume it is once only — extensions and workplace changes can require a new one.
- If a result comes back abnormal, get advice the same week — the criminal track moves independently of the visa track.
