The Expat Syndrome follows a predictable timeline:
Months 0-3: Conscious incompetence. You know you don't know. Ask questions. Listen. Take notes. Operate cautiously.
Months 4-6: Peak false confidence. Surface familiarity feels like understanding. You've navigated traffic, made local friends, know restaurant prices. The gap between "I understand this city" and "I understand how systems work" collapses.
Months 7-12: Operational mistakes. Wrong assumptions about enforcement patterns. Misread political triggers. Misjudge stakeholder dynamics. The cost of overconfidence becomes visible.
Why it's dangerous: You stop asking questions precisely when you need to ask more. Local networks become invisible because you think you already see them. Formal rules feel sufficient because informal enforcement patterns are now "normal background noise" instead of critical decision variables.
The mechanism is universal but intensity varies by region.
