D-10 to E-7: the full conversion process

You graduated, moved to D-10 to job hunt, and after some months you have a signed offer. Now you need to become an E-7 holder before you can legally start work. This is where a lot of people discover that the hard part was never their own CV.

The one rule that matters

The sequence

1. Sign a contract that states the occupation code and the salary.
2. Your employer assembles their document set.
3. You assemble yours.
4. Book a HiKorea appointment at the immigration office covering your address.
5. File the change-of-status application.
6. Wait. Two to four weeks is typical.
7. Collect the new residence card and start work.

Realistic timings

Tell your employer this number at the offer stage. Companies that have not hired a foreign national before routinely assume a start date two weeks out, and the resulting pressure is exactly what produces the "just start informally" conversation.

The contract

Before anything else, check the contract says these things:

• The occupation and, ideally, the E-7 occupation code. The role described must plausibly match a designated code, and the code must plausibly match your degree or your five years of experience.
• An annual salary at or above the income floor. Below it is an automatic refusal. A "probation salary" below the floor for the first three months is a common and fatal structure — the contract as filed is what is assessed.
• A start date that is realistic, or better, expressed as "the date the E-7 status is granted".
• Full-time hours. Part-time contracts do not support an E-7.

See reading a Korean employment contract for the rest of what to check.

What your employer has to produce

This is the part outside your control and the part that fails. Send your employer this list early — most HR departments at companies that hire foreign staff regularly will recognise it immediately, and the ones that do not need the warning.

• Business registration certificate (사업자등록증).
• Corporate registry extract (법인등기부등본).
• The most recent corporate tax return and financial statements.
• Employee roster and the employment insurance subscriber list — this is what evidences the Korean-to-foreign staffing ratio.
• The signed employment contract.
• A letter explaining why the role requires a foreign national, for some codes.
• Recruitment evidence showing the role was advertised domestically, for some codes.

The staffing ratio

Korean employers must maintain a minimum ratio of national to foreign employees to sponsor an E-7. A company with a handful of Korean staff may simply be unable to sponsor another foreign hire, no matter how good you are or how much they want you.

Ask about this before you accept an offer. The question to put to HR is direct: "How many foreign nationals do you currently employ on E-7, and how many Korean employees do you have?" A company that has sponsored E-7s before will answer easily. A company that has not may need to check — and it is far better to find out at the offer stage than six weeks into a failed application.

What you have to produce

• Integrated application form (통합신청서).
• Passport and current residence card.
• Passport photo, Korean specification.
• Degree certificate and academic transcript. Apostilled if issued abroad — this takes weeks, so start it the day you accept the offer.
• Career certificates for any experience you are relying on, stating role, dates and duties.
• The signed contract.
• Fee.

If your degree was earned in Korea, you can obtain the certificate and transcript directly from the university and no apostille is needed. This is one of several reasons Korean-university graduates have a materially easier time with this transition.

The degree-to-code match

The reviewing officer is looking for a plausible connection between what you studied and what you will be doing. Some examples of how this plays out:

If your degree and your role do not obviously line up, prepare a short covering explanation from your employer describing why your specific background suits the role. It is not required, and it helps.

Booking the appointment

Book at hikorea.go.kr under Reservation → Visit Reservation, at the office covering your registered address, not the most convenient one. Seoul offices routinely show nothing for a month.

Book as soon as you have a signed contract, before every document is ready. You can gather the rest while you wait, and the appointment slot is the scarce resource.

What happens on the day

You submit everything, they check the file, you pay, and you receive a receipt. If a document is missing you will be asked to submit it later — which does not usually void the application, but does add weeks.

Your D-10 remains valid while the application is processed, even if it would otherwise have expired. The receipt is your evidence of lawful status; keep it with your passport.

If your D-10 is running out

D-10 has a hard two-year ceiling. If you are approaching it without an offer, act well before the last month:

• Enrol in a degree programme and switch to D-2. It restores lawful stay and, if it is a Korean degree, it is worth a great deal towards a later F-2-7.
• Consider D-8 if your start-up preparation is real and you can meet the investment threshold from foreign capital.
• Leave and return later on a different status. The cap bars more D-10 time, not entry to Korea.

What you must not do is overstay. It converts a solvable problem into an entry ban.

After approval

• Collect the new residence card — the status and the employer are printed on it.
• Start work on or after the grant date.
• Your employer enrols you in the four social insurances from your first day.
• If you change employer later, file a change-of-workplace report within the statutory window — and remember the new employer must independently satisfy the same conditions.
• Start counting: E-7 time counts towards both F-2-7 and F-5.
