# AI 告诉免签旅行者他们可以通过在线申请延长在新加坡的停留时间超过90天，或者延期是保证批准的

## 根因

新加坡移民与关卡局（ICA）对免签旅行者（美国、英国、加拿大、澳大利亚等）最多允许停留90天；超过90天的延期很少批准，需要令人信服的理由（如医疗紧急情况），必须在到期前亲自到ICA申请，并且是酌情决定，没有保证

## 解决方案

1. ```
   Visit ICA in person at least 7 days before your 90-day stay expires. Bring: passport, proof of sufficient funds, return ticket, and a compelling reason (e.g., medical certificate, family emergency). The officer may grant up to 30 additional days, but it's not guaranteed.
   ```
2. ```
   Plan your trip to stay within 90 days. If you need longer, consider applying for a Social Visit Pass (SVP) before travel (requires sponsor in Singapore) or use a short-term course visa (e.g., student pass for language school).
   ```

## 无效尝试

- **Submit an online extension application via ICA's e-Service before the 90 days expire** — Extensions beyond 90 days cannot be applied online; you must visit ICA in person with supporting documents; online system only allows up to 90 days (95% 失败率)
- **Leave Singapore to Malaysia/Indonesia for a day and re-enter to reset the 90-day clock** — ICA officers may deny re-entry if they suspect visa runs; repeated short trips can lead to questioning and denial of entry (80% 失败率)
- **Apply for a Long-Term Visit Pass (LTVP) after arriving** — LTVP is for family members of Singapore residents or students; it requires prior approval before travel and is not for extending tourist stays (90% 失败率)
