Korea Extra Activities Permit: Can You Legally Take a…

The second job offer looks great. Almost.

You hold a valid visa. A second company wants you two evenings a week. Or a university asks you to give a paid guest lecture. It feels like simple extra income.

To Korean immigration, it can look like illegal work.

You may have already said yes. Maybe you’ve even signed something. Now you’re staring at HiKorea forms that seem to describe three different situations at once. That confusion is normal, and it’s fixable. The key is knowing which permit fits your case before you work a single hour.

Why does a small side job put your visa at risk?

Your visa covers one set of activities. Anything that falls under a different status of sojourn needs a separate permit, called cheryu jagyeok oe hwaldong heoga (permission for activities outside your status of sojourn). Without it, even one weekend shift counts as unauthorized work. The legal basis is Article 20 of the Immigration Act, and approval must come first.

Here is the official wording.

“A foreigner who intends to engage in activities falling under any other status of sojourn, along with the activities permitted under his or her status of sojourn, shall obtain permission therefor from the Minister of Justice in advance, as prescribed by Presidential Decree.” (Immigration Act, Article 20, English translation via MOLEG)

Two words matter most. In advance. Approval that arrives after you started does not clean up the days you already worked.

Who usually needs it

The permit matters most if your visa ties you to one purpose or one employer:

• D-2 and D-4 students taking part-time jobs (the student part-time work permission is a version of this permit)
• D-10 job seekers taking an internship or short-term paid work
• E-1 to E-7 professionals doing work that belongs to a different visa type
• D-8 investors doing paid work outside their own business

Who usually doesn’t

F-5 (permanent residence) and F-6 (marriage migrant) holders generally have no employment restrictions. Many F-2 categories also carry broad work rights. F-4 overseas Koreans can work in most fields, but simple labor jobs are restricted. Check the exact sub-code on your ARC (Alien Registration Card) before you assume you’re free.

So what counts as “another status”? Picture the visa that would fit the new job if it were your only job. An E-7 software engineer teaching evening English classes is doing E-2 work. A D-2 student consulting for a startup is doing E-7-type work.

Here’s the catch. For E-7 holders, a second job might not trigger Article 20 at all. It can fall under a different rule with a different deadline.

E-7 second job permit: is it Article 20 or Article 21?

If the second job uses the same E-7 occupation code, you’re adding a workplace. That’s Article 21, known as geunmucheo chuga (workplace addition). If the second job belongs to another visa type, like E-2 English teaching, you need the Article 20 extra activities permit instead. Filing under the wrong article is one of the easiest ways to lose weeks.

Article 21 of the Immigration Act covers changing or adding a workplace within your current status. It has a twist. The general rule is prior permission from the Minister of Justice. But the law lets foreigners with professional knowledge or skills, as listed in the Enforcement Decree, report within 15 days after the change or addition instead.

Which group are you in? The Enforcement Decree of the Immigration Act lists the qualifying statuses, and some E-7 job codes carry extra conditions. Don’t guess. Call the Immigration Contact Center at 1345, or ask your local office, and confirm whether your job code allows reporting.

What concurrent employment approval means in practice

HR teams often call this concurrent employment approval. They mean one thing: immigration must know both employers exist. Your main sponsor usually has to sign a consent letter. Without it, most offices won’t accept a workplace addition file. Ask for that letter first. It’s often the slowest piece.

Your main employer has its own interests, too. Many Korean employment contracts limit side work. Immigration approval does not override your contract. E-7 visa job change

You’ve found the right form. Next question: what will it cost you? The government fee is the smallest part.

What does the application fee really cost you?

The government fee is KRW 120,000 per application, per the fee schedule on HiKorea. It applies to the extra activities permit and to workplace change or addition permits. Student part-time work permission is generally processed free of charge. The fee itself is predictable. The real costs are time, paperwork, and the income you lose while you wait.

At most offices, you pay with a revenue stamp, called suip inji, bought on site. Bring a card and some cash in case the machine is busy.

Three costs most applicants miss

1. Lost work time. Immigration offices run on weekday business hours. Most require a visit reservation through HiKorea, and slots in Seoul can fill up weeks ahead. Plan for at least half a day off.
2. Translation and authentication. If your degree or certificates aren’t in Korean or English, the office can ask for a translation. Foreign degrees may also need an apostille or consular confirmation.
3. A delayed start. You can’t begin until approval comes through. If the new employer expects you next Monday, you may lose those first paychecks. Tell the employer the realistic timeline up front.

Then there’s the paperwork. That’s where most files stall.

Which required documents get files sent back?

Every file starts with the Integrated Application Form, your passport, your ARC, and the fee. Then you prove the new job is real and suits you: a contract, the employer’s business registration, your qualifications, and, for workplace additions, your main employer’s consent. Missing consent letters and outdated employer certificates are what most often send applicants home to try again.

Core documents

• Integrated Application Form (Form No. 34 under the Enforcement Rule of the Immigration Act)
• Passport and ARC
• Fee of KRW 120,000, unless your case is exempt

Documents about the new activity

• Employment contract with the second employer, showing duties, hours, pay, and period
• The second employer’s business registration certificate
• A consent letter from your current employer (essential for workplace additions)
• Proof you’re qualified for the new duties, such as a degree, license, or career certificate
• At some offices, the employer’s national and local tax payment certificates

Employers issue national tax certificates through the National Tax Service Hometax system. Local tax certificates come from Government24. For D-2 students, the university’s international office usually has to confirm the job first.

Step-by-step application

1. Confirm your rule (Article 20 or Article 21) with 1345 or your local office.
2. Get the signed consent letter from your main employer.
3. Collect the second employer’s documents. Check the issue dates, since many offices want recent certificates.
4. Book a visit reservation on HiKorea. Some cases, including student part-time permission, can be filed as an e-application instead.
5. Attend the appointment, submit the file, and pay the fee.
6. Wait for the decision. Don’t start work until approval shows on your record.

Even a complete file can fail, though. Here’s why.

Reasons for rejection: why do complete files still fail?

Officers have discretion, so no checklist guarantees approval. Most refusals trace back to six problems: you already started working, the job is simple labor, the second employer doesn’t qualify, your main employer won’t consent, your own record has issues, or the hours crowd out your main activity. All but the first can be fixed before you apply.

1. You already started

This one hurts most. Contract dates, payslips, or insurance enrollment can show you worked before approval. Then the application can turn into an investigation. Under Article 94 of the Immigration Act, unauthorized activity is punishable by up to 3 years in prison or a fine of up to KRW 30 million. Article 46 also allows deportation. Employers who hire without permission face penalties, too.

2. The job is simple labor

Professional visas exist for professional work. A factory or delivery shift on the side rarely fits E-series rules. F-4 holders face the same limit on simple labor.

3. The second employer doesn’t qualify

E-7 sponsors are screened on business size, tax compliance, and how many foreign staff they hire compared with Korean staff. A second employer adding you generally faces the same checks. Newly registered or tax-delinquent companies often fail here.

4. No consent from your main employer

No letter, no workplace addition. Most offices stop the file at the counter.

5. Your own record

Unpaid taxes, past Immigration Act fines, or an overstay history all weigh against you. So does a stay period that’s about to end. The permit can’t run past your current period of stay, so extend first if you’re close. Korea visa extension

6. The hours crowd out your main activity

For students, too many hours suggest work has replaced study. For E-7 holders, a second role that looks full-time raises questions about the first job.

No file is bulletproof. But you control most of these risks before you ever walk in.

How should you apply this week?

Start with one phone call to the Immigration Contact Center at 1345. Confirm which article applies to you. Then secure your main employer’s consent, collect the second employer’s documents, and book a HiKorea visit. Tell the new employer your start date depends on approval. That one sentence protects you more than any document in the file.

A simple plan:

• Day 1: Call 1345. Give your visa code and the second job’s duties. Ask which rule applies and whether you can report instead of applying.
• Day 2: Request the consent letter in writing.
• Days 3 to 5: Gather the second employer’s certificates and your qualification documents.
• Day 5: Book the earliest HiKorea visit reservation you can get.

The line is available in English and several other languages. Keep copies of everything you submit.

Refused? Ask the officer which ground applied. Most grounds, apart from work done before approval, can be fixed before you reapply.
