D-10-3 (Advanced Technology Intern) Korea Visa Guide | 2026

1. What D-10-3 Is

D-10-3 sits within the job-seeking (D-10) status but is distinct in purpose from its siblings: D-10-1 is 일반구직, general job seeking; D-10-2 is 기술창업준비, technology startup preparation; D-10-T is 최우수인재, the preliminary Top-Tier code. D-10-3 exists specifically for advanced-technology internship activity at a company or institution meeting the Ministry of Justice's requirements.

2. Eligibility Checklist

• The internship is in an advanced-technology field.
• The host company or institution meets the requirements set by the Minister of Justice.
• This is internship activity — if you are looking for work generally, D-10-1 is the code; if you are preparing a technology startup, D-10-2.
• No unresolved compliance issues block review.
