## 根因

英国标准访客签证（包括 6 个月多次入境）不可延长，除非在特殊情况下（如医疗紧急情况）根据移民规则附录 V；逾期停留即使 1 天也会触发《移民法》第 10 条规定的 12 个月禁止入境，且与爱尔兰的共同旅行区（CTA）不会重置时间

## 解决方案

1. ```
   If exceptional circumstances apply (e.g., medical emergency), apply for an extension using form FLR(IR) but select 'Exceptional Circumstances' and attach evidence (e.g., hospital letter). Submit via UKVI online: https://www.gov.uk/standard-visitor-visa/extend-your-visa
   ```
2. ```
   Leave the UK before the 6-month visa expires and apply for a new Standard Visitor visa from your home country; the new visa grants a fresh 6-month period. Use the UKVI portal: https://www.gov.uk/apply-uk-visa
   ```
3. ```
   For long-term stays, apply for a Long-term Standard Visitor visa (2, 5, or 10 years) from outside the UK before travel; this allows multiple entries with max 6 months per visit but no per-visit gap requirement
   ```

## 无效尝试

- **** — FLR(IR) forms are for family or private life routes (e.g., spouse visa), not for visitor visas; the UKVI system will reject the application outright, and the fee (£1,048) is non-refundable (99% 失败率)
- **** — The Common Travel Area (CTA) allows free movement between UK and Ireland, but the UK Border Force counts total time in the CTA; re-entering from Ireland does not reset the 6-month clock, and the traveler is still considered overstaying if they exceed 6 months in the UK (95% 失败率)
- **** — The UKVI explicitly states that Standard Visitor visas cannot be extended for tourism; only 'exceptional circumstances' (e.g., hospitalization, court appearance) are considered, requiring documentary proof (e.g., medical letter) (97% 失败率)
