根因分析
美国免签计划（VWP）严格禁止通过在美国境内申请将身份更改为 B-2（旅游签证）来延长 90 天的停留时间；唯一的例外是在特殊情况下（例如医疗紧急情况）通过正式申请（I-539），这种情况很少被批准，如果被拒绝，需要立即离开美国。
English
The US Visa Waiver Program (VWP) strictly prohibits extending a 90-day stay by applying for a change of status to B-2 (tourist visa) while in the US; the only exception is for extraordinary circumstances (e.g., medical emergency) through a formal application (I-539), which is rarely approved and requires leaving the US immediately if denied.

-
如果您需要停留超过 90 天，请在 90 天之前离开美国，并在本国的大使馆/领事馆申请 B-2 旅游签证。B-2 签证允许停留最多 6 个月，并且如果需要，可以通过 I-539 延长。
-
如果您有紧急情况（例如医疗治疗），请在第三国（例如加拿大）的美国领事馆申请 B-2 签证，并提供紧急情况的证明，但请注意批准不保证，您可能需要等待处理。
无效尝试
常见但无效的做法:
-
File Form I-539 (Application to Extend/Change Nonimmigrant Status) while on ESTA, claiming you want to stay longer for tourism
98% 失败
USCIS will deny the application because ESTA is not a visa and does not allow change of status; you must leave the US and apply for a B-2 visa from your home country.
-
Leave the US to Canada or Mexico for a weekend and re-enter on ESTA, assuming the 90-day clock resets
95% 失败
CBP considers ESTA entries as part of a single visit; leaving to Canada/Mexico does not reset the clock, and re-entry may be denied if the total time in the US exceeds 90 days.
-
Apply for an extension online through the ESTA system, claiming it allows extensions
99% 失败
The ESTA system does not have an extension feature; it is only for pre-travel authorization, not for extending stays.
