As is often noted on the Visa forum, agent assisted extensions of stay are often or usually sent upcountry from the more populated expat locations. This with the assistance of Gemini as to the 'investigation' in the OP: When an immigration office in a smaller Thai province starts processing an unusually high number of extensions using Clause 5 of Royal Thai Police Order No. 327/2557, it inevitably triggers a cascade of institutional red flags. To understand why, you have to look at what Clause 5 actually is: it is the discretionary fallback clause. It allows a senior officer (inspector grade or higher) to recommend an extension of stay for a foreigner who fails to meet standard criteria (e.g., retirement, marriage, or standard employment) if they believe a "legitimate reason" exists. When a small province experiences a spike in these specific waivers, the consequences generally unfold in (three) distinct phases: Central Bureau Audits & Red Flags Small provincial immigration offices are expected to handle predictable, low-volume workloads. When data tracking at the central Immigration Bureau in Bangkok shows a statistical anomaly—like a sudden surge in non-standard discretionary approvals from a quiet province—it signals a high probability of "visa farming" or local administrative non-compliance.
