Korea Long-Term Visa Types: How D, E, and F Codes Decide…

It all comes down to one letter.

D, E, or F. Your school or employer probably picked it for you, and year one went fine. Then you wanted to change jobs, bring a partner, or stay after graduation. Suddenly the code on your card said no.

Nobody explains this part at the start. A Korean visa isn’t just permission to be here. It’s a lane. Some lanes lead to permanent residence. Others stop after a fixed number of years, no matter how carefully you follow the rules.

This guide compares the long-term codes using what the Korea Immigration Service and HiKorea publish. You’ll see which lane you’re in, where it leads, and the step where most plans break. Korea visa application process

Why does the letter on your visa matter more than the number?

Korea sorts long-term stays by letter. D codes cover study, training, and business activity such as investment. E codes cover paid employment, from professors (E-1) to professionals (E-7) to factory workers hired through the Employment Permit System (E-9). F codes cover residence and family ties. H codes cover working visits. The letter sets your work rights, your family options, and your path forward.

Korea visa type comparison: D, E, and F codes side by side

The Korea visa category list the Immigration Office uses has dozens of sub-codes. For long stays, four families matter.

D codes are activity visas. You hold a D-2 because you’re enrolled at a university. A D-4 covers language study and some training programs. A D-10 gives graduates and qualified professionals time to look for a job. A D-8 investor visa requires at least 100 million won of foreign direct investment in a Korean company. Work on most D codes is limited and usually needs separate permission.

E codes are tied to one job. An E-1 professor, an E-2 foreign language instructor, and an E-7 professional all hold status because of a specific role. The employer is part of your application. Quit, and your status doesn’t simply transfer to a new job. You need approval first.

F codes are the flexible ones. F-2 residents, F-4 overseas Koreans, and F-6 marriage migrants can work in a wide range of jobs. F-4 still bars some simple labor roles. F-5 is permanent residence. It’s where most lanes are trying to end.

Why does this matter so much? Because the letter decides what you can do next, not just today.

So which code actually gets you to year five? That depends on where you start.

Which Korea visa for staying long term? Look at the exit, not the entry

The best long-term visa is the one with a clear next step. A D-2 student can move to D-10, then E-7, then F-2 or F-5. An E-9 worker can convert to the E-7-4 skilled worker visa through a points test. An F-6 marriage migrant can apply for F-5 after two years. Codes without an onward step cap your stay.

Most people judge a visa by what it lets them do right now. That’s the trap. Ask a different question instead. What can this code turn into?

Four common lanes

1. The student lane. D-2 (or D-4 for language study) moves to D-10 after graduation, then to E-7 once you land a qualifying job. From E-7, many professionals aim for F-2-7, then F-5.
2. The worker lane. E-9 workers hired through the Employment Permit System can stay up to 4 years and 10 months per employment cycle. Re-entry is possible for some. The E-7-4 skilled worker conversion is the main route past that cap.
3. The family lane. F-6 covers spouses of Korean citizens and leads to F-5. Spouses and minor children of F-5 holders usually receive F-2-3.
4. The heritage lane. F-4 is for overseas Koreans, meaning foreign citizens of Korean descent. It’s renewable and has its own F-5 route. H-2 working visit status serves some overseas Koreans from China and former Soviet countries.

Here’s the catch. Time served matters. The general F-5 track requires 5 years of legal residence on qualifying statuses. Study years on D-2 usually don’t count toward that total.

That makes graduation a real deadline. A D-2 student who finishes without a job offer has to move to D-10 or leave. Missing that window is one of the most common ways a long-term plan ends early. D-10 job seeker visa

For most professionals, the lane runs through F-2. And F-2 has a reputation it doesn’t fully deserve.

Why do people think F-2 is out of reach?

The F-2 residence visa has several sub-types, and the best known, F-2-7, uses a points system. You need at least 80 points across age, education, Korean ability, and annual income. Most applicants also need to hold a qualifying professional status, such as E-7, at the time they apply. Bonus points come from KIIP completion and other factors.

People hear points system and picture a PhD plus fluent Korean. The real table is more forgiving. It also rewards things you can still change.

What the Korea residence visa F-2 requirements actually score

• Age. Applicants in their late twenties and early thirties score highest. Points drop with age.
• Education. A bachelor’s degree earns points. A master’s or doctorate earns more.
• Korean ability. TOPIK levels or KIIP stage completion. Higher levels mean more points.
• Annual income. Scored by bracket and proven with tax records from the National Tax Service.
• Extras and deductions. Some items, such as a degree from a Korean university, add bonus points. Immigration or criminal violations subtract them.

Which of these can you move this year? Age, no. Income moves slowly. Korean ability is the lever you control most.

The Korea Immigration and Integration Program (KIIP) runs classes and stage exams, often on evenings and weekends. Completing stages pays off twice. It adds F-2-7 points now, and most F-5 tracks later require proof of Korean language and basic social knowledge. KIIP program guide

Other doors into F-2

F-2-7 isn’t the only route. F-2-3 covers family of permanent residents, as noted above. Other sub-types exist for specific groups, and each has its own document list on HiKorea. The Ministry of Justice updates the F-2-7 table, so open the current notice before you count your points.

Scoring 80 doesn’t finish the job, though. You still have to switch status. That’s where most files fall apart.

The step where most applicants get rejected: changing status

A change of status is permission to swap one visa code for another without leaving Korea. Under Article 24 of the Immigration Act, you must apply before your current stay expires, at the immigration office covering your address. Not every swap is allowed. Short-term visitors on C-3 or visa-free entry generally cannot switch to a long-term code, with narrow exceptions.

Korea visa change of status eligibility: three checks

Run these three checks before you book anything.

1. Is the move allowed at all? Some transitions are routine, such as D-10 to E-7. Others can’t be done inside Korea. In those cases, you leave and apply for a new visa at a Korean embassy or consulate. C-3 visa status change exceptions
2. Do you qualify on the day you apply? Not next month. Your offer letter, degree certificate, and salary terms must be ready when you file.
3. Is your record clean? Overstays, unreported job changes, tax arrears, and unpaid health insurance premiums can all count against you.

Where files actually fail

Here’s what actually happens in a typical refusal. The application looks complete. But one piece doesn’t match the rules for the new code.

• Job mismatch. The job title doesn’t fit an E-7 occupation code, even if the work itself is skilled.
• Salary too low. E-7 salaries must meet a floor tied to Korea’s per-capita gross national income (GNI). The Ministry of Justice updates it yearly.
• Paperwork gaps. Foreign degrees often need an apostille or consular confirmation, plus a translation.
• Late filing. Applying after your stay expires isn’t a status change. It’s an overstay.

Most immigration offices (churipguk oegugincheong) require a booked appointment through HiKorea. Some status changes can also be filed online through HiKorea e-application.

One more point. A complete file is not a guarantee. Immigration officers have discretion and can ask for more documents.

Say you’re approved. Two clocks start right away, and one of them isn’t printed on anything you’ve been handed yet.

What starts ticking after approval?

Two clocks. First, anyone entering on a long-term visa must register as a foreigner within 90 days of entry and receive a residence card, often called an ARC. Second, your permitted stay has an end date. You can apply for an extension starting 4 months before it expires. Missing either deadline risks fines and future refusals.

The first clock comes straight from the law.

Any foreigner who intends to stay in the Republic of Korea for more than 90 days from the date of his/her entry shall register as a foreigner with the chief of the competent immigration office having jurisdiction over his/her place of stay… within 90 days from the date of his/her entry.

Immigration Act, Article 31 (English translation via MOLEG)

Registration gives you the residence card, still widely called the ARC (oegugin deungnokjeung). When you change status inside Korea, the card is updated to show your new code. Keep your address current too. Moving without reporting it is a common, avoidable violation.

The second clock is your stay end date. HiKorea accepts extension applications from four months before expiry up to the expiry date itself. Waiting until the last week leaves no time to fix a missing document.

Then there’s health insurance. Foreign residents staying 6 months or more are generally enrolled in National Health Insurance automatically. Premiums arrive monthly. Leave them unpaid, and your next extension may come back shorter than you asked for. That’s the record check from the last section, showing up again.

So where should you start? It depends on the card in your wallet right now.

Your next move, based on the card in your wallet

Your next move depends on the code you hold today. Pick one target code, then work backward from its requirements: degree, salary, Korean ability, and time served. Check the qualifying list on HiKorea before you assume a jump is possible. Keep tax and insurance records clean, and put the extension window on your calendar the day your card arrives.

Here’s what that looks like by code.

• D-2 or D-4: Map your graduation date to the D-10 application window. Start the job search in your final year, not after.
• E-9: Ask your employer about E-7-4 eligibility well before you reach the 4 years and 10 months cap.
• E-7: Score yourself against the F-2-7 table now. If you’re short, Korean ability is the fastest fix.
• F-6: Start KIIP early. The F-5 language requirement is easier to meet over two years than in two months.
• F-4: Compare ongoing F-4 renewals with the F-5 route. Permanent residence ends the renewal cycle.

Before any application, check the latest rules on HiKorea and the statute text on MOLEG. Rules change, and the official page always wins over any summary, this one included. F-5 permanent residency

Your lane starts with a letter. Where it ends is still up to you.
