Employer-Sponsored Work Visas

This page is about how sponsorship actually works - what your employer files, what you have to prove, and how a workplace change is approved. The map of which statuses exist is on Korean visa types; this is the mechanics of getting and keeping an employment-based one.

The central fact: your employer is a party to your immigration status, not a bystander. Their paperwork, their finances and their compliance all bear on whether you get the visa and whether you keep it.

How sponsorship runs

The efficient route, used for most employment categories, works like this:

1. You receive an offer and a signed contract.
2. Your employer applies in Korea for a confirmation that a visa may be issued to you, submitting their own company documents alongside yours.
3. Immigration assesses the employer as well as you - whether the business is real and trading, whether the role genuinely requires a foreign worker, and whether the company meets any thresholds for its category.
4. A confirmation number is issued to the employer, who passes it to you.
5. You apply at a Korean mission with that number, which is far quicker than a cold application.
6. You arrive, then register and collect your residence card within 90 days. The residence card covers that.

If you are already in Korea on another status, the equivalent is a change of status at an immigration office rather than leaving and returning. Whether that is permitted depends on both statuses, and short-stay visitors generally cannot convert to work status from inside the country.

What you have to prove

Document	Note
Degree certificate and transcript	Authenticated, and often required sealed or direct from the institution
Evidence of experience	Career certificates from previous employers, with dates and duties
Criminal record check	Required for teaching and childcare categories; authenticated
Health or medical check	Required for some categories
Passport and photographs	Plus the application form and fee

Authentication is the slow step and it starts in the country that issued the document - an apostille where your country is party to the convention, consular legalisation where it is not. It takes weeks and cannot be done from Seoul.

Order spare certified copies while you are at it. The same documents are wanted again at renewal, at a change of employer, and at any later residence application. Extending your stay covers that.

What the employer has to satisfy

Worth knowing because it explains refusals that have nothing to do with you:

• A genuine, registered, trading business, with tax filings in order.
• Thresholds for the category, which can include a minimum salary for the role and limits on the ratio of foreign to Korean employees.
• A role that matches an approved occupation, with your qualifications matching it.
• Compliance history, including whether they have properly enrolled and paid for previous employees.

Smaller companies sometimes discover mid-process that they do not qualify. If an employer is evasive about the category or the timeline, that is worth probing before you resign from anything.

Qualification matching, which is where it fails

The commonest substantive refusal is a mismatch between your qualification and the occupation. A degree in an unrelated field, for a role that requires a specific one, is a problem no amount of enthusiasm fixes. Relevant documented experience can substitute in some categories, which is why career certificates matter.

Get this checked before the employer files, not after. The free multilingual immigration helpline will discuss your specific combination, and that call is worth making early. Immigration offices and overstay covers the helpline.

Looking for work from inside Korea

There is a dedicated job-seeking status for graduates and qualified people, assessed on a points basis, which permits you to stay and look rather than leave and apply. It is time-limited, permits limited activity including internships, and is the normal bridge from graduation to employment.

The usual path for an international graduate is study status, then job-seeking status, then an employer-sponsored one. International students covers the sequence, and campus life in Korea the years before it.

Renewal, and keeping the status

Sponsorship is not a one-off event. At each extension the office looks again at both of you: whether the company is still trading and compliant, whether you are still doing the approved role, and whether the income still meets the category.

Which produces one piece of advice worth more than the rest: keep your own file. Your contract, payslips, insurance enrolment record, career certificates and authenticated documents, in one place, updated as things arrive. Employers lose paperwork, companies restructure, and HR staff leave. The person with the folder renews in an afternoon.

Extending your stay in Korea covers the window and the refusal causes, several of which are the employer's doing rather than yours.

Changing employer

On an employer-tied status, get approval before you start the new role. Starting first and filing later is the mistake that turns a routine move into a status problem.

What is required varies: some categories need express permission, others a notification within a set period. Either way the new employer must be eligible to sponsor your category, which means the same assessment runs again on them.

Where the reason for leaving is the employer's fault - unpaid wages, closure, mistreatment - that is generally treated differently from an ordinary move, which is precisely why you document the reason at the time. Your rights as a worker covers it.

Where this goes wrong

• Starting document authentication late. It is always the long pole.
• A qualification that does not match the occupation. Check before filing.
• Resigning before the new sponsorship is approved.
• Assuming a tourist visit converts to work status from inside Korea.
• An employer vague about the category or suggesting you start meanwhile.
• No career certificates from previous jobs to evidence experience.
