“I had an MBA and 11+ years of global experience. The Korean bank still treated me like a ghost.”
Hello and welcome to JS Network. My name is Colin, and I’m probably not the “Korea Expert” you’re used to.
You’re here because you’re facing a problem. A “Nightmare.”
Maybe your landlord is trying to keep your **deposit (보증금)**. Maybe you’re an “invisible” ghost with a **zero credit score (신용점수)**. Maybe your foreign credit card failed the **T-Money machine** again, or you’re tangled in the **eSIM vs. USIM** trap. Or perhaps you’re trying to start a **K-Beauty business** and hitting regulatory brick walls.
I know, because I’ve been there. I’ve lived that “Expat Nightmare” for over a decade.
Why JS Network is Different (My Origin Story)
I’m not a typical blogger or a simple tour guide. I am a **CEO** of a Korean corporation, a **U.S. MBA** graduate, and have **11+ years of experience in high-level global sales** (Oil & Gas).
And when I first came to Korea, *none of that mattered*.
I faced the same absurd challenges every foreigner does. I was an “expert” in the boardroom but a “beginner” at the bank. I spent the last 10 years reverse-engineering the ‘system’—not just the business side, but the everyday ‘nightmares’ that no one prepares you for.
I learned that losing your deposit isn’t just ‘bad luck’—it’s failing to get one stamp (Hwakjeong Ilja). I learned that building a credit score wasn’t impossible—it just required a ‘cheat code’ (non-banking info submission).
JS Network (`jsnetwork.co.kr`) was born from that frustration. It was created to be the **’Expert Guide’** and **’Trusted Partner’** I wish I’d had. This isn’t just a “blog.” This is a decade’s worth of ‘Nightmare Solutions’—all in one place.
What This “Nightmare Solver” Does For You
My mission is simple: To provide the solutions, whether it’s free information or a hands-on professional service. I focus on the three areas where expats and businesses truly ‘get stuck’.

1. Free Expert Guides (The Blog)
First, the information. My 32+ (and growing) ‘Nightmare Solution’ guides are the foundation of JS Network. This is where you find the answers to Visa, Housing, Banking, and daily life challenges—all free.
2. Global Trade & B2B Solutions (The ‘MBA’ Service)
For international companies needing a reliable, MBA-qualified partner in the Korean market. This is where my 11+ years in global sales come in.
- B2B Market Entry (Inbound/Outbound)
- Market Research & B2B Sales Representation
- Online B2C Store Management (I run my own ㅋㅋㅋ)
- K-Beauty Import/Export Consulting
3. K-Product Sourcing & Premium Concierge (The ‘CEO’ Service)
For businesses and discerning individuals who value time and results. When you’re too busy to handle the ‘nightmare’ yourself, I handle it for you—personally and professionally.
- Guaranteed Sourcing (K-Pop, K-Beauty, ‘that one specific item’)
- Secure Local Purchasing & Export/Import Logistics
- Premium Travel & Concierge: Full itinerary planning, difficult local bookings, and administrative errand running (the “fixer”).
Stop Searching. Start Solving.
Whether you are reading our free guides or hiring me for a **premium project**, my goal is the same: To turn your Korean ‘Nightmare’ into a success story.
