My previous employer refuses to sign a release letter. Am I stuck?

Not necessarily, and the framing is worth correcting first. Immigration needs to establish that the previous employment genuinely ended and on what basis. A signed document from the old employer is a convenient way to show that, which is why it is asked for — but it is evidence of a fact, not a consent the old company is entitled to withhold. Where it is refused, the question becomes whether the same fact can be shown another way: the contract, a termination or non-renewal notice, final payslips, insured status records, or a labour office record.

What can I use instead?

Anything that independently evidences the end of the relationship and its reason. The employment contract and its term, written notice of dismissal or non-renewal, resignation correspondence, final pay and severance records, the loss of insured status on employment insurance and health insurance, and any record from the labour office if unpaid wages or a breach were involved. Your former employer also has its own obligation to report the change to immigration, so in many cases the fact of the ending reaches immigration without the document you were asked for.

Can my old company be penalised for not reporting my departure?

Yes. Reporting a change in a foreign national’s employment within 15 days is the employer’s duty under the Immigration Act, and failing to do it exposes them to an administrative fine of up to ₩2,000,000. That is worth knowing for two reasons: it confirms the 15-day period is theirs rather than yours, and it explains why a company that is refusing a courtesy letter may still complete a filing it is actually required to make.

Is this the same on E-9?

No, and the stakes are different. On E-9 the reason the job ended does not only prove that it ended — it decides whether a workplace change is permitted at all, and whether the move counts against your limited number of changes. A move forced by closure, unpaid wages, breach of working conditions or unfair treatment may not count; the same departure recorded as voluntary may. So on E-9 the evidence is doing two jobs, and it is worth assembling before you leave rather than after.

When Your Old Employer Will Not Release You

Published October 16, 2026Last verified October 16, 2026

A release letter is

Evidence, not consent

Employer’s own duty

Report within 15 days

Missing that

Fine up to ₩2,000,000

On E-9

The ground may not count

Ask about changing jobs in Korea on a work visa and someone will eventually mention a release letter — a document from the previous employer confirming they have let you go. Then the sentence that follows is usually wrong: that without it, you cannot move.

The document is real. The veto is not.

What is actually being asked for

Reframing this changes what you do next

"My old employer must approve my move." Not a legal position.

"Immigration must be satisfied the old job ended, and how." That is the actual requirement.

A signed letter is the convenient proof — which means other proof exists.

An evidence problem has alternatives. A consent problem does not.

Change the question and the refusal stops being final.

Why the document is asked for at all

When a workplace change is assessed, part of what has to be established is that the previous employment relationship genuinely ended, and on what basis.

A letter from the previous employer — a release, a termination confirmation, a certificate of employment, a resignation acknowledgement — settles that quickly and in one page. That convenience is why it is requested so consistently, and why it gets mistaken for a requirement in its own right.

The distinction that matters

A consent requirement would mean your former employer holds a right to decide. An evidentiary requirement means a fact has to be shown. Facts can be shown more than one way — which is the entire difference between "I am stuck" and "I need another document".

What else evidences the same fact

Where the letter is refused, work the fact rather than the form:

The employment contract — its term, and any fixed end date.

Written notice of dismissal or non-renewal. Dismissal must be given in writing with the grounds and the date, so if you were dismissed there should be a document.

Resignation correspondence, including the acknowledgement or anything showing it was requested by the company.

Final pay and severance records — a final settlement is hard to explain if the relationship continued.

Loss of insured status on employment insurance and health insurance, with the date.

Labour office records, where unpaid wages or a breach of conditions was involved.

You can also request a certificate of employment — the Labor Standards Act entitles an employee to one covering matters such as period of employment and position, on request, and an employer’s willingness to issue a routine certificate is often different from its willingness to sign a letter framed as permission.

Your former employer has its own filing to make

Independently of anything you ask for, an employer must report to immigration within 15 days when employment with a foreign national ends. Missing it exposes them to an administrative fine of up to ₩2,000,000.

Two useful consequences

First, it confirms whose the 15 days actually are — the employer's, not a countdown imposed on you. Second, a company refusing a courtesy letter may still complete a filing it is legally required to make, so the fact that you left can reach immigration without the document you were denied.

Where closure or non-payment is the reason

If the company shut down, stopped paying, or breached the contract, the release letter was never going to arrive — and that is precisely the case the evidence route is for.

Business closure records, unpaid wage claims, a labour office complaint, insured status ending abruptly across a workforce: these establish both that the employment ended and why, without the cooperation of the party responsible.

On E-9 the reason does a second job

For a professional status, the reason mainly establishes that the relationship ended. On E-9 it also decides whether a change is permitted at all — the grounds are limited to statutory ones — and whether the move counts against the change allowance.

Which is why an E-9 worker should assemble it early

A departure recorded as voluntary can both fail the grounds test and consume one of a small number of permitted moves. A departure evidenced as closure, unpaid wages, breach of working conditions or unfair treatment may do neither. The difference is documentary, and it is far easier to gather while still employed than afterwards.

What not to do

Do not start work while negotiating for the letter. The missing document is a paperwork problem; working without permission is an immigration offence — see changing employers on a Korean work visa.

Do not sign something inaccurate to obtain it. A statement that you resigned voluntarily, given to unlock a letter, can undo a job-seeking benefit claim and, on E-9, a workplace change.

Do not accept a payment condition. Any demand to repay training costs or a sum for the release is a contract question with its own limits, and a predetermined penalty for leaving is prohibited outright.

Do not let it stall the clock. On E-9 especially, the application and permission deadlines run whether or not the letter has arrived.

The prohibition on penalties fixed in advance for breach of contract, and what a training-cost clause can and cannot do, is in your Korean employment contract.

If you are already in the argument

Ask in writing, naming the document and the facts it needs to confirm. A refusal in writing is itself evidence.

Assemble the alternatives from the list above, with dates.

Ask immigration what it will accept — 1345, in several languages — rather than assuming the letter is mandatory.

Where unpaid wages or a breach is involved, raise it with the labour office on 1350. That produces a record, which is what you were short of.

A former employer who will not sign has made your next step harder. Whether they have made it impossible depends on what else you can show — and the answer is usually more than people expect, because the fact you need to prove is one that leaves traces in payroll, in insurance records, and in the employer’s own obligation to report it.
