感谢板主跟板友分享的情报
我这边也顺利延长了
分享一下需要的资料
The U.S. address where you are located.
A brief explanation of the I-94 error, including the date of entry,
port of entry, Airline and flight.
A color PDF file of your Passport biographic page.
A color PDF file of your Visa page.
A color PDF file of your Admission Stamp page.
(If a stamp was provided at entry)
A PDF file of any documents associated with your visa, ie I-20, DS-2019, I-797.
如果是ESTA,就不需要visa页面
还需要的是班机的取消证明
**For Visa Waiver ESTA travelers requesting Satisfactory Departure, please
attach your passport biographic page and proof of cancelled flight.**
寄了两个地方都有提到这些
可能是现在的标准程序
顺便一提
申请时卡在航班的取消证明很久
因为UA没发通知就改了航班
照程序去申请取消证明要7-14个工作天
跟他们说有居留期限的问题也说没办法帮忙
联合航空这方面让人感觉很糟
有这方面需求的人请尽早处理航班取消证明
