If you are a foreign national living in South Korea, the most efficient way to handle your administrative requirements is to learn how to manage Korea Immigration Service residency online. Instead of visiting a local immigration office in person, you can use a suite of digital tools—primarily the Hi Korea portal, the Gov.kr e-government platform, and the official Mobile ID application—to extend visas, renew residence cards, and report changes in your living situation. Using these tools reduces wait times and eliminates the need for many physical appointments.
Which digital platforms should I use for immigration tasks?

Depending on the specific task, you will need to use different portals. The South Korean government has split immigration services between a specialized immigration portal and a general administrative portal.
Hi Korea (hikorea.go.kr)
Hi Korea is the central hub for most visa and residency-related activities. This is the primary site you will use for the following tasks:
- Applying for extensions of stay (visa extensions).
- Applying for the renewal of your Alien Registration Card (ARC) or Domestic Residence Card.
- General inquiries regarding immigration policies and electronic forms.
Gov.kr (The e-Government Portal)
While Hi Korea handles the “visa” side of residency, Gov.kr is used for broader administrative reporting. For foreign residents, this portal is essential for reporting changes in your personal details or residence address without having to visit a community center or immigration office.
Korea Mobile ID Application
For those who prefer digital credentials over physical cards, the official Korea Mobile ID app allows residents to carry a digital version of their residence card. This is increasingly accepted for identity verification across various sectors.
How do I update my residence address online?

Reporting a change of address is one of the most critical legal obligations for foreign residents. By law, you must report a change in your place of residence within 15 days of moving. Failure to do so can result in fines or complications during your next visa extension.
To update your address online, follow these steps:
- Log in to the Gov.kr portal.
- Navigate to the “Foreign Resident Change of Address Report” (외국인 체류지변경신고) section.
- Enter your new address details and upload any required proof of residence (such as a housing contract).
- Submit the application and check the processing status through the portal.
Alternatively, you may use the Hi Korea portal for similar reporting tasks. If you are unable to use the digital portals, you can visit the immigration office or the community center (Dong-samuso) governing your new address.
How can I verify a foreign residence card?
There are scenarios where third parties—such as landlords, employers, or service providers—need to verify that a residence card is valid and authentic. To facilitate this, the Korea Immigration Service provides a Foreign Residence Card Verification Service.
This service has expanded beyond the banking sector to include various non-banking sectors, making it easier for foreign nationals to access financial and administrative services. The verification allows the service provider to confirm the residency status of the cardholder through the official immigration database, reducing the need for the resident to provide multiple physical copies of their registration certificates.
How do I get and use the Mobile Residence Card?
The Mobile Residence Card is a digital version of the physical ARC/Residence Card. It is designed to provide the same legal effect as the physical card for identity verification in most everyday situations.
How to issue the Mobile ID
To obtain the digital card, you must download the official Korea Mobile ID application. The process generally requires:
- A smartphone registered in your name.
- A valid physical Residence Card.
- Identity verification through a certified digital certificate (public key certificate).
Practical use of the Mobile ID
Once issued, the Mobile Residence Card can be used for identity checks at government offices, some financial institutions, and other service providers. However, it is recommended to keep your physical card as a backup, as some smaller establishments may still require a physical document.
What to do when digital tools are not enough?
While the digital systems are comprehensive, certain complex cases—such as specific visa changes or legal disputes—may require human intervention. If you encounter a technical error on Hi Korea or Gov.kr, or if your specific situation is not covered by the online forms, use the following resources:
The 1345 Immigration Contact Center
The 1345 center is the official helpline for all immigration-related inquiries. It provides support in multiple languages, helping you navigate the digital tools or directing you to the correct physical office. You can call 1345 from any phone within Korea.
Visiting the Local Immigration Office
Some tasks still require a physical visit. Always check if an appointment is required via Hi Korea before visiting, as most immigration offices now operate on a strict reservation-only basis.
Frequently Asked Questions
What happens if I miss the 15-day deadline for reporting a move?
Missing the deadline can lead to administrative fines. If you realize you are late, it is better to report the change immediately via Gov.kr or Hi Korea rather than waiting. The fine amount varies depending on the length of the delay.
Can I apply for a new ARC entirely online?
While you can often start the application process or upload documents via Hi Korea, the initial registration for a first-time ARC usually requires a physical visit to provide biometric data (fingerprints) and submit your passport.
Which digital certificate is needed for Gov.kr?
To use the full range of services on Gov.kr, you typically need a joint certificate (formerly known as a public key certificate) or a simple authentication method (such as Kakao, Naver, or Toss) linked to a phone number registered in your name.
Next steps for foreign residents
To ensure your residency remains in good standing, we recommend taking these practical steps immediately:
- Create accounts: Register on both Hi Korea and Gov.kr.
- Set up authentication: Ensure you have a verified digital certificate or a mobile authentication method linked to your Korean phone number.
- Download the Mobile ID app: Set up your Mobile Residence Card to have a digital backup of your identity.
- Calendar the 15-day rule: If you move, set a reminder to report your change of address immediately to avoid fines.
