ARC Photo Requirements in Korea: Size, Background, and Why…

One photo can stall your whole visit.

You booked a slot on HiKorea. You gathered your passport, your school or job papers, and the fee. Then you look at the photo you brought from home. It’s a square US-style passport photo. Will it pass? It won’t. That small mismatch sends a lot of applicants home for a second appointment.

The ARC (Alien Registration Card, now officially called the Residence Card, or oegugin deungnokjeung in Korean) is the ID you’ll use for bank accounts, phone plans, and the National Health Insurance Service. D-2 and D-10 students, E-7 and F-2 workers, and F-6 or F-5 marriage migrants all need one. F-4 overseas Koreans who report domestic residence face the same photo standard. ARC application process

The legal basis is short. The Immigration Act, available in English on MOLEG, sets the rule:

Any foreigner who intends to stay in the Republic of Korea for a period exceeding 90 days from the date of his/her entry … shall register as a foreigner with the head of the competent immigration office. (Immigration Act, Article 31)

The photo is a tiny part of that registration. It’s also one of the easiest parts to get wrong. Here’s the catch: the rules are stricter than they look.

What size and background does Immigration actually accept?

The accepted photo size and background are simple on paper. Your photo must be 3.5 cm wide by 4.5 cm tall, in color, on a plain white background, and taken within the last 6 months. You must face the camera directly. Korea uses the same core specs for passport photos, so every Korean photo studio already knows them.

HiKorea, the immigration portal run by the Ministry of Justice, lists a photo as a standard item for foreigner registration. Korean studios follow the passport photo standard published by the Ministry of Foreign Affairs on the Korean passport portal. A photo that meets that standard is the safe choice for your ARC.

Here are the core specs in one place:

• Size: 3.5 cm x 4.5 cm (width x height)
• Head height: 3.2 to 3.6 cm, from the top of the head to the chin
• Background: plain white, with no patterns, gradients, or shadows
• Age of photo: taken within the last 6 months
• Color: full color, not black and white
• Print: on photo paper, not plain office paper

Notice the head-height rule. It’s the one people forget. A photo can be the right size overall and still fail. Why? Your face is too small inside the frame.

Bring at least one photo for the application. A spare costs very little. It also saves stress if the officer asks for another.

So why doesn’t the photo you already have count? The answer is in the measurements.

Why your home-country passport photo won’t always work

Many countries use different photo sizes. A US passport photo is 2 x 2 inches (about 5.1 x 5.1 cm), which is square. Korea wants a 3.5 x 4.5 cm rectangle. Trimming a square photo changes the head size and the framing. UK photos match the size but use a cream or light grey background, which is not white.

So what should you do? Get a fresh photo in Korea. It’s fast.

Look for a sajingwan (photo studio) near your home or your immigration office. Ask for a yeogwon sajin (passport photo). That one phrase tells the photographer the exact size and background you need. Most studios print several copies at once. Many will also send you the digital file if you ask.

Self-service photo booths sit in many subway stations and shopping malls. Some have a passport or ID mode. Check that the output is 3.5 x 4.5 cm with a white background before you pay.

Here’s a quick comparison:

Size and background are the easy part. The next part is where officers look closely.

What do officers check on your face at the counter?

Officers check your face, not just the frame. Your expression should be neutral, with your mouth closed and both eyes open. Your full face, from forehead to chin, and the top of your shoulders must be visible. Tinted lenses, glare on glasses, and hats are not accepted. Religious headwear is the exception, as long as your face stays fully visible.

Here’s what actually happens at the counter. The officer holds your photo next to your passport and your face. If those three don’t look like the same person, the photo becomes a problem.

That’s why these details matter:

• Glasses: Clear lenses are fine if there’s no glare and the frames don’t cover your eyes. Tinted lenses and sunglasses are not accepted. If in doubt, take them off.
• Hair: It must not cover your eyes or the outline of your face.
• Headwear: Religious head coverings are accepted when your face is fully visible. Fashion hats and caps are not.
• Expression: Neutral. No wide smile. No open mouth.
• Lighting: Even light, with no shadows on your face or behind your head.
• Clothing: A white top can blend into a white background. A darker top gives a clean outline.

One local issue deserves its own note. Korean studios often retouch photos by default. They call it bojeong (editing or correction). Light cleanup is normal. Heavy skin smoothing, face slimming, or a changed eye shape is not. Those edits can make you look like a different person. Ask for minimal editing. A short phrase works: bojeong jogeumman (just a little editing).

But what if you never hand over a printed photo at all? Online applications have their own traps.

Applying online? The digital photo file specs that trip people up

Some HiKorea e-applications ask you to upload a photo instead of handing in a print. The digital photo file specifications follow the same standard: a 3.5 x 4.5 cm portrait shape, white background, full color, and taken within 6 months. Save the file as a JPG. The upload screen shows the exact file size limit, so check it before you scan or export.

The ratio matters more than the pixel count. A 3.5 x 4.5 cm photo has a 7:9 width-to-height ratio. Crop it to a different shape and the image can come out stretched or squashed.

Follow these steps to prepare the file:

1. Ask your photo studio for the digital file when you pick up your print. This is the cleanest source.
2. If you only have a print, scan it at 300 dpi. That gives about 413 x 531 pixels, which keeps the 7:9 ratio.
3. Crop only if needed. Don’t cut into the top of your head or your chin.
4. Save as JPG. Compare the file size with the limit on the upload page.
5. Don’t upload a phone screenshot of a photo. Screenshots add borders and lose sharpness.
6. Don’t use filters, beauty modes, or background-removal apps.

A good file gets you through the first application. But your card won’t stay the same forever. What happens when it needs replacing?

Do you need a new photo when you renew or replace your card?

You need a new photo whenever a new card gets printed. That includes reissuance after a lost or damaged card, and changes to the personal details shown on the card. A change of status, such as D-10 to E-7, also changes what’s printed. For photo requirements for renewal application, check the HiKorea document list for your exact task.

Here’s the rule that catches people. The 6-month limit applies every single time. The photo on your current card is almost certainly older than that. You can’t reuse it. You also can’t photograph your old card and print the result.

Some common situations:

• Lost or stolen card: Apply for reissuance at your immigration office within 14 days of the loss. Bring a new photo, your passport, and the fee.
• Damaged card: Same process. Bring the damaged card with you.
• Change of status (for example, D-2 to D-10, or D-10 to E-7): Your new status appears on the card. Bring a fresh photo with your other documents.
• Extension of stay: Requirements differ by visa type. Read the document list for your visa code on HiKorea. Then bring a photo anyway. It’s cheap insurance.

The Korea Immigration Service runs the 1345 Immigration Contact Center. It answers questions in English and many other languages. Call 1345 if your situation doesn’t fit the list above. From a foreign phone number, dial +82-1345. lost ARC reissuance

Now you know when you need a photo. The last piece is knowing exactly why one gets turned down.

Which rejection reasons for ARC photos cause a second trip?

The rejection reasons for ARC photos come down to six problems: a background that isn’t white, a photo older than 6 months, the wrong size, a head that’s too small or too large, shadows or glare, and heavy retouching. Each one takes minutes to fix at a photo studio. Checking all six before you leave home saves a repeat appointment.

Two more problems are worth avoiding. Photos printed on plain paper at home look blurry and curl at the edges. Photos with another person cropped out show uneven borders. Neither is worth the risk.

But it gets worse if you wait. The 90-day registration deadline in the Immigration Act doesn’t pause because of a photo problem. A rejected photo on day 88 can push you past the limit. Book early and leave yourself room for one retake.
