D-2 vs. D-4: What’s the Difference? A Complete Guide to Choosing the Right Korean Student Visa

1. What Are the D-2 and D-4 Visas?

Korea’s student visa system is divided into two major categories, each designed for different study purposes:

• D-4 Visa: For students attending Korean language programs.

• D-2 Visa: For those studying degree programs at colleges, universities, or graduate schools.

These two visas are the most common for Vietnamese students, yet many applicants confuse them because some requirements look similar.
