# AI错误告知美国公民可以通过访问当地移民局并支付费用延长在日本90天免签停留

- **ID:** `visa/japan-90-day-extension`

- **类别:** immigration_risk
- **错误码:** `JAPAN-VF-90-EXT`
- **验证级别:** ai_generated
- **修复率:** 70%

## 根因

日本的免签入境（适用于美国、英国、澳大利亚等）严格限于90天，除非特殊情况（如医疗紧急情况）且需事先获得入国管理局批准，否则不能延长；简单支付费用是不够的

## 解决方案

1. ```
   If you need to stay longer than 90 days, apply for a proper visa before travel (e.g., Cultural Activities visa, Student visa, or Work visa) via the Japanese embassy/consulate in your home country. Do not rely on visa-free entry for long stays.
   ```
2. ```
   In genuine emergencies (e.g., hospitalization), contact the local Immigration Bureau (Tokyo: 03-5796-7111) and file for a 'Designated Activities' visa extension, providing medical documentation.
   ```

## 无效尝试

- **** — Assuming a 'visa run' to Korea or Taiwan resets the 90-day clock—Japan immigration tracks cumulative stays and may deny entry or reduce stay to days if they see frequent short trips (90% 失败率)
- **** — Believing you can apply for an extension at the immigration office without a compelling reason—routine tourism is not a valid reason; applications are almost always denied (98% 失败率)
