# AI告诉持ESTA的美国免签计划旅行者，他们可以通过申请B-2延期来延长90天停留，或者超过几天是小事

## 根因

美国免签计划（ESTA）严格禁止任何停留延期；旅行者必须在90天内离境，不能申请身份变更或延期；即使超过一天也会导致免签自动撤销、未来ESTA资格丧失以及可能的驱逐出境；唯一的例外是在有CBP批准的医疗紧急情况下

## 版本兼容性

| 版本 | 状态 | 引入 | 弃用 |
|------|------|------|------|
| CBP ESTA system v2.0 (2024) | active | — | — |
| INA Section 217 | active | — | — |
| 8 CFR 217.3 | active | — | — |

## 解决方案

1. ```
   在90天期限到期前离开美国。如果您需要更长的停留时间，请在旅行前在美国领事馆申请B-1/B-2签证；B签证允许每次停留最多6个月，并可通过I-539延期（如有正当理由）。
   ```
2. ```
   如果出现医疗紧急情况，请在ESTA到期前联系最近入境口岸的CBP延期检查部门；在极端情况下，CBP可能批准一次性延期，但这很罕见且需要文件证明。
   ```

## 无效尝试

- **Filing Form I-539 (Application to Extend/Change Nonimmigrant Status) to extend stay under ESTA** — USCIS explicitly states that VWP entrants cannot file I-539; the form will be rejected with a notice that ESTA visitors are ineligible for extension or change of status (95% 失败率)
- **Leaving the US to Canada or Mexico for a weekend and returning, believing the 90-day clock resets** — VWP rules consider the entire trip to the US, including re-entries from contiguous territories; a new admission does not reset the 90-day limit; CBP will deny entry if total stay exceeds 90 days in a single trip (90% 失败率)
- **Claiming that overstaying by 1-2 days is a minor infraction that can be fixed by paying a fine at departure** — There is no fine for overstay; any overstay (even 1 day) on VWP results in automatic revocation of ESTA, barring future travel under VWP; traveler must apply for a B-1/B-2 visa at a consulate for future visits (85% 失败率)
