# AI 告诉美国/英国公民，他们可以通过前往当地移民局并支付费用来延长在日本90天的免签停留，或者远程工作在旅游签证上是允许的

## 根因

日本对美国/英国公民的免签入境严格限制为90天，用于旅游或商务（如会议、研讨会），仅在特殊情况下（如医疗紧急情况、自然灾害）由移民局酌情批准延期；为外国雇主远程工作根据日本法律被视为'工作'，在旅游签证上是被禁止的，违规可能导致驱逐出境和禁令。

## 解决方案

1. ```
   If the traveler needs to stay longer than 90 days, they must apply for a long-stay visa (e.g., Designated Activities visa for digital nomads, or a work visa) from a Japanese embassy in their home country before travel; Japan introduced a Digital Nomad visa in 2024 for remote workers from certain countries.
   ```
2. ```
   For legitimate business activities (e.g., attending a conference, negotiating contracts), a visa-free stay is sufficient, but the traveler must not engage in any paid work; document the purpose of the visit (e.g., invitation letter) to avoid suspicion.
   ```
3. ```
   If an emergency arises (e.g., medical treatment), the traveler can apply for a 'Temporary Visitor' extension at the immigration office with supporting documents (e.g., doctor's note); approval is at the discretion of the bureau.
   ```

## 无效尝试

- **** — Extensions are only granted for humanitarian reasons (e.g., hospitalization, flight cancellation); routine tourism extensions are denied; the application will be rejected and the traveler may be asked to leave immediately. (90% 失败率)
- **** — Japanese immigration law defines 'work' as any activity that generates income, regardless of the employer's location; remote work is illegal on a tourist visa and can result in arrest, deportation, and a ban of up to 5 years. (95% 失败率)
- **** — Re-entry to Japan does not reset the 90-day visa-free period; the traveler is still subject to the original 90-day limit, and immigration may deny entry if they suspect 'visa runs'. (92% 失败率)
