Consultation details and bookingIf the category is unclear, you do not need to choose a service name first. A free initial review can help identify what should be checked in your situation.
Yes. We begin with the actual activity, operator, premises, and transaction structure rather than relying on a label.
We separate the facts presented and each authority's jurisdiction, then organize the questions that still need written confirmation.
We connect the Korean operating entity, investment or company structure, immigration status, and operating permits in the order relevant to the model.
The review does not assume a permit is required, but it also checks whether a notification, registration, or another statutory duty may remain.
This is general information only; feasibility and procedures require case-by-case review and confirmation with the official agency.
Review common requirements and practical issues before you file.

“While preparing to launch an online hold'em game, we were very worried about where to apply for a rating and what would happen if the game were judged speculative. The attorney explained which body, GCRB or GRAC, has jurisdiction over our game and why, citing the relevant law, which set our direction clearly.
In particular, the clear explanation of the difference between "games with speculative content" and "speculative games" let us check in advance how to design our game money and cash-out structure to avoid a rating refusal. Knowing the expected review period and the objection procedure ahead of time helped us plan our business schedule far more reliably.”
