## 根因

泰国允许免签入境30天（大多数国籍，如美国、英国、加拿大）从陆地边境，或60天从机场（2024年起）；超过初始期限的延期需要签证（例如旅游签证TR）或仅在持旅游签证入境时可在移民局延期30天（费用1,900泰铢），免签入境不适用；逾期罚款每天500泰铢，但可能导致驱逐和禁令

## 解决方案

1. ```
   如果需要停留超过30天，在旅行前向泰国大使馆或领事馆申请旅游签证（TR）。该签证允许最多60天，可在移民局延期30天（费用1,900泰铢）。例如：美国公民在华盛顿泰国大使馆申请TR，获得60天签证，然后在泰国移民局延期。
   ```
2. ```
   如果已在泰国免签入境，前往邻国（如老挝、柬埔寨）并在那里的泰国大使馆申请旅游签证（例如万象、老挝）。处理时间1-2天。
   ```
3. ```
   因紧急情况（如疾病）需要短期延期最多7天，前往泰国移民局并凭医生证明申请“考虑停留”（费用1,900泰铢）。此为酌情决定。
   ```

## 无效尝试

- **Traveler enters Thailand visa-free at a land border (30 days) and later tries to extend for another 30 days at immigration office, assuming it's automatic** — Visa-free entries cannot be extended beyond the initial 30-day period; only Tourist Visa holders can apply for a 30-day extension at immigration (95% 失败率)
- **Traveler overstays 10 days, pays the fine of 5,000 THB, and assumes they can re-enter immediately** — Overstaying can result in a re-entry ban (e.g., 1 year for overstay >90 days); even short overstays may be flagged, and immigration may deny re-entry (80% 失败率)
- **Traveler does a visa run to a neighboring country (e.g., Malaysia) and re-enters Thailand on the same day, expecting a new 30-day stamp** — Thai immigration may limit the number of visa-free entries per year (e.g., 2 land entries per calendar year) and may deny entry for frequent visa runs (70% 失败率)
