From BTS and Squid Game to K-dramas and Korea’s café culture — global interest in Korea is growing rapidly, and more foreigners are visiting than ever before.

However, when you search for Korea visa types, you’ll find plenty of information but very little about the real-life issues people face while living in Korea.
This article focuses on practical tips and real examples to help foreigners better understand visa types and overcome common challenges during their stay.

Korea visa types: Key categories and important tips for living in Korea

Short vs Long Term Visas and Visa Run Tips

Korea visa types are generally divided into two categories: short-term visas for temporary stays such as tourism or business trips, and long-term visas for extended stays such as studying, working, or marriage.

Short-term visas allow stays of up to 90 days for tourism, business, or events.Long-term visas are for stays longer than 90 days, such as education, employment, or family purposes.

The C-3 short-term visa is designed for tourism and visits, allowing a maximum stay of 90 days. You can join brief training or experience programs, but full-time study or employment is not permitted.

Keep in mind that paid work or employment is strictly prohibited under short-term visas, and you cannot stay beyond 90 days.

Some people try to extend their stay by leaving Korea briefly and re-entering — for example, visiting Japan or Taiwan right before their visa expires. This practice, known as a “visa run,” may be viewed by Korean immigration authorities as a violation of the purpose of stay. Repeated visa runs may cause entry restrictions or even visa denial in the future.

Extending Your Stay on a Short-Term Visa

Sometimes, visitors who come to Korea on a short-term visa want to stay a little longer. This is especially common for those who decide to continue studying in Korea after arriving. In such cases, rather than repeating visa runs, it’s safest to go through the official process of switching from a short-term visa to a long-term one.

1. Switching from a Short-Term Visa to a Student Visa (D-2)

If you decide to study in Korea, you can change your C-3 (tourist) visa to a D-2 (student) visa. Completing this process legally allows you to stay and continue your studies safely.

When to apply: Before your current visa expiresHow to apply: Online via the Hi Korea websiteRequired documents: Passport, certificate of admission, proof of finances (e.g., bank balance certificate), ID photo

💡 Tip
: During the review process, immigration officers focus on verifying your genuine intention to study. If your admission or financial documents are incomplete, your application may be rejected—so make sure everything is in order.

2. Extending Your Stay on a Tourist Visa

You can also request an extension at an immigration office by providing valid proof of your purpose for staying longer. Approval depends on how clearly you can justify your reason for the extension.

Recommended supporting documents

Certificate of enrollment (or proof of upcoming admission)Housing contract (e.g., dormitory or share house)Academic schedule or tuition payment receipt

These documents show that you are legally preparing for study in Korea, allowing you to extend your stay without relying on visa runs. Next, let’s look at common issues and solutions for those planning a long-term stay in Korea under different Korea visa types.

Korea visa types: Top 3 Common Visa Questions and How to Solve Them

Q1. What if I’m on a student visa but want to stay in Korea after graduation?

Even if your visa has not yet expired, your student visa automatically ends upon graduation. In most cases, you must either leave Korea within 2 to 4 weeks, continue to a higher academic program, or change your visa status—typically to a job-seeking visa (D-10) to stay legally in the country.

If you have your passport, graduation (or expected graduation) certificate, and proof of finances, you can apply online. Once approved, your visa will be converted, allowing you to remain in Korea for up to one year.

📌 Application Summary

Q2. What should I do if I lose my job or change employers while holding a work visa (E-7, E-2, etc.)

In Korea, many foreigners work as English teachers. Those holding an E-7 (specialized profession) or E-2 (English instructor) visa may face uncertainty in their visa status if their contract ends or they decide to change jobs.

There are two ways to handle this situation

Find a new employer within the 90-day grace period and report your updated employment contract.Convert your visa to a D-10 (job-seeking) visa within the same 90-day period, which allows you to legally stay in Korea for up to one year while seeking a new job.

💡 Tip: If your employment changes, you must report the new contract within 30 days. Failure to do so can result in visa extension denial later on.

If you fail to take either of these steps within 90 days, you may be considered to be staying illegally in Korea.

Q3. What are the common mistakes people make when applying for permanent residency (F-5)

Many long-term residents in Korea aim to obtain permanent residency (F-5), but quite a few applications are rejected due to tax issues or gaps in visa history. To increase your approval chances, review this checklist carefully before applying

📌 Checklist

Submit proof of full payment of national and local taxesProvide income and employment records for the past three yearsMaintain a continuous visa history without gaps

Requirements may vary depending on your visa type and purpose of stay, so it’s a good idea to check with Hi Korea in advance
