What is the Basic Trading Course (OASIS 4+)?

A basic trading course the operator publishes on its trade visa (D-9-1) page, described as equipping foreigners with basic importing and exporting for a start-up. Its certificate scores 10 points in the D-9-1 trade-expertise pool. It is a different course from the D-8-4 OASIS-4 Basic Start-up Class.

How many points is the OASIS 4+ certificate worth on the D-9-1 matrix?

10 points, inside the trade-expertise pool that holds up to 35 points. Working experience scores 20 and a university major scores 15. The prerequisite pools for D-9-1 hold up to 65 points, and the award target is 60 out of 160.

How long is the course and when does it open?

The operator prints 25 hours over 3 full days and opens a new cohort every quarter. The printed day headers (8, 9, 8 hours) disagree with the printed module sums (8.5, 9, 8.5); the page reconciles neither.

Is the course taught in Korean?

Yes. The operator prints that all courses are provided in the Korean language. That differs from the D-8-4 OASIS courses, which are provided in a proper language for participants.

What does the D-9-1 trade visa require beyond points?

The page lists TOPIK 3 or higher, 60 points or more out of 160, a required item score of 10 or more, and a business (individual) registration certificate. The registration must classify as trade business, with a lease contract for an independent business establishment under the applicant's name.

Can I use the OASIS 4+ certificate on the D-8-4 start-up visa matrix instead?

The two pages print different items. The D-8-4 elective table carries OASIS-1, OASIS-2 and OASIS-4 with no OASIS 4+ label, and the D-9-1 trade-expertise pool carries the Basic Trading Course certificate. The operator prints no mechanism for carrying one across the other.

Does the basic trading course help with visa extension?

The page ties the trade visa extension to trade records — extension permission for long-term residents runs from actual trade performance, on a separate extension points table. The printed extension items list trade performance, Korean employees, tax performance and completion of the advanced trade training course. No extension-listed item names the basic certificate.

OASIS 4+ Basic Trading Course: the 10-point certificate on Korea trade visa (D-9-1) points matrix

OASIS 4+ 기본 교역 과정 — D-9-1 교역 비자 매트릭스의 10점

Published 19 September 20265 min read2 primary sources

On the operator trade visa (D-9-1) page — a different matrix from the D-8-4 — the Basic Trading Course (OASIS 4+) certificate scores 10 points in the trade-expertise pool. The operator prints 25 hours over 3 full days, in Korean, open every quarter. The printed day totals and the printed modules disagree on the operator's own page.

The three printed days of the Basic Trading Course (OASIS 4+) with their printed hour headers and module sums — 8 against 8.5, 9 against 9, and 8 against 8.5 — beside the trade-expertise pool where the certificate scores 10 points

The operator runs a second visa system. The Startup VISA (D-8-4) page scores company founders. A separate page covers the trade visa D-9-1, and it carries its own points matrix and its own course.

The same centre runs both. The operator's header on the D-9-1 page describes a system that evaluates professionalism and domestic sojourn experience for foreign traders, and ties visa extension to actual trade records.

This post covers what that page prints about the course — format, syllabus, and where its 10 points sit.

The course and who it reaches

The operator's listing names it Basic Trading Course (OASIS 4+), described as a basic trading course for foreigners equipped with basic importing and exporting for a start-up.

Three printed format facts:

A total of 25 hours over 3 full days.
All courses are provided in the Korean language.
Every quarter opens a new cohort.

The course sits in the same Training Program section as the extension recommendation letter and the advanced trade training course.

The printed syllabus, hours as printed

Day 1 (printed 8 hours)	Day 2 (printed 9 hours)	Day 3 (printed 8 hours)
Orientation and course introduction 0.5h	Understanding and practice of target marketing 2.0h	Advanced understanding of Korean society 2.0h
Understanding of immigration laws 2.0h	Business management and tax system in trade 2.0h	Trade laws and regulations 3.0h
Import and export business process 3.0h	Trade document preparation 3.0h	Trade agreement 3.0h
Online trade concept 3.0h	Trade payment 2.0h	Survey and closing ceremony 0.5h

The printed module hours sum to 8.5, 9 and 8.5 across the three days. The headers print 8, 9 and 8. The printed course total reads 25 hours; the modules add to 26.

Where the 10 points sit on the D-9-1 matrix

The prerequisite pool holds up to 65 points, split into two printed halves. The trade-performance half prints four figure bands — export records at USD $300K+ and USD $100K–$300K, import-plus-export records at USD $500K+ and USD $300K–$500K.

Against those bands the table prints four scores: 30, 20, 15 and 10, in the order shown.

The trade-expertise half reads cleanly:

Trade-expertise item	Points
Working experience	20
University major	15
Basic Trading Course (OASIS4+) certificate	10

Elective pools add period of stay (up to 20), education background (up to 20) and additional points (up to 55). The operator's own 60-point worked example pairs the certificate with a Korean college degree (5), Korean education background (30) and a 3-year-plus stay (15).

The name, and where it does not point

The OASIS 4+ label sounds like the OASIS-4 on the start-up page. They are different courses. The D-8-4 OASIS-4 is the Basic Start-up Class, 20 printed hours across business topics.

The D-9-1 course prints a three-day trade syllabus. The operator uses the same OASIS numbering across the two systems without printing a link between them. If a staff conversation covers both visas, name the visa first.

The operator's schedule page lists each course round. The live calendar aggregates the published rounds as they open.

When it runs, and how to apply

The schedule page prints six open rounds of the trade course across the year. Each carries an application window, an announcement date and three class days, Thursday to Saturday.

Selection is by committee review of the business item you submit, with the result sent by email. The programme is for founders who have graduated from a Korean college or university, and it is taught in Korean.

The submission rules are unusually explicit. The operator asks for your own account of your progress and plans, within two thousand characters.

Submissions found to be written by AI, copied from templates or written by someone else may be penalised. There is no set form, and the operator says it judges readiness rather than writing skill.
