Adéquation aux critères d'éligibilité
Je remplis les conditions essentielles du visa D-3 et je comprends les exigences applicables en matière de parrainage, de diplôme, de revenu, de situation familiale ou d'expérience.
The D-3 visa (기술연수 — technical training) is for foreign workers who come to Korea to receive on-the-job technical training at a Korean industrial company. It is strictly tied to an existing business relationship: the trainee must be an employee of an overseas subsidiary or joint venture of the Korean company, or work for a foreign firm that has licensed Korean technology or imported Korean-made industrial plant worth the statutory minimum threshold. The D-3 is not a general skills-training visa — it is a company-to-company knowledge-transfer instrument. All D-3 visas must be sponsored through a 사증발급인정서.
Production-line workers employed by a company that is an overseas subsidiary or joint venture of a Korean industrial firm, or a foreign firm that has imported Korean technology (USD $100,000+ technology license) or industrial plant (USD $500,000+). Must be personally unable to acquire the required technical skills in their home country.
Employed by the overseas subsidiary/joint-venture or partner firm that qualifies the host Korean company for the D-3 programme
Korean host company has a qualifying relationship: overseas direct investment under 외국환거래법, technology export contract of USD $100,000+, or plant export of USD $500,000+ under 대외무역법
Training is necessary because the technology cannot be taught outside Korea
Host Korean company must be a registered industrial establishment (기술연수업체)
Trainee is a production-level worker, not a manager or admin
Korean-language ability documentation may be required
Risques de retard et de refus
Business-investor cases are document-heavy because immigration reviews both the legal investment route and the real business activity.
D-8 review can stall when the investment amount, sender, receiving company, bank trail, foreign-exchange documents, or investor identity do not line up cleanly.
Base du manuel : The D-8 manual references investment funds, remittance/payment evidence, foreign-investment registration, and related supporting documents.
Company registration alone is not enough. Thin operating records, no real business activity, or weak continuity evidence can invite additional review.
Base du manuel : The stay manual includes D-8 extension and business-continuity review points for investor status management.
Some industries or business structures are restricted or do not fit the claimed D-8 route. A filing built around the wrong route can be refused or redirected.
Base du manuel : The D-8 sections refer to restricted industries and cases where the applicant is not considered essential management or production-technology personnel.
If relying on a technology startup pathway, OASIS, IP, corporate setup, and founder activity evidence must support the specific route claimed.
Base du manuel : The manual separates investor and technology-startup founder pathways and lists different documentary expectations.

Il s'agit de facteurs de risque pratiques pour le Technical Trainee Visa, et non d'une liste exhaustive des motifs légaux de refus. L'examen final peut varier selon la nationalité, le canal de dépôt, le consulat, le bureau de l'immigration et les circonstances propres à chaque dossier.

Procédure de visa
Carte d'enregistrement des étrangers (ARC)
La carte d'enregistrement des étrangers (ARC) est la pièce d'identité officielle délivrée aux ressortissants étrangers séjournant en Corée du Sud pendant 91 jours ou plus. Elle est indispensable pour ouvrir un compte bancaire, souscrire un forfait téléphonique et accéder à la plupart des services publics.

Procédure de visa
Prolongation de visa (체류기간 연장)
Une prolongation de visa — officiellement appelée « prolongation de la période de séjour » (체류기간 연장) dans le droit coréen de l'immigration — permet à un étranger de rester légalement en Corée au-delà de la date d'expiration de son visa ou de son ARC, sans quitter le pays.
Procédure de visa
Changement de statut de séjour (체류자격 변경)
Un changement de statut de séjour permet à un étranger déjà présent en Corée du Sud de passer d'une catégorie de visa à une autre sans quitter le pays — par exemple, d'un visa étudiant D-2 à un visa de travailleur qualifié E-7 après l'obtention du diplôme et l'embauche.
D-3 is a training visa, not a pathway to a work visa by default. However, if you develop skills that qualify you for an E-series work visa (e.g., E-7), your training experience could support a future application. Speak to an 행정사.
The number of D-3 trainees a Korean company can host is capped per a quota formula set by immigration authorities, based on the company's qualifying investment or technology-export amounts. A single company may host trainees from multiple overseas partner companies, but the total cannot exceed the company's aggregate quota.
