有網友私信，所以朋友將經驗分享如下:
我是直接寫信去給 CBP 在 LAX
CBP 回覆時附上兩個 Forms , 還有其他需要的文件，
：那兩個 Forms 要印出來簽名，不可以用電子簽名
Satisfactory Departure_ Request Form
I94_Affidavit
For a complete applicatoin, you will need:
(1) passport biographical page, (2) original departure flight itinerary, (3)
proof that airline cancelled flight due to COVID-19 related issues (Travel
ban, airport closures, decreased flight operation, etc.) and (4) booking
confirmation for future departure (Future travel must be the next “available
flight” out of the United States) (5) satisfactory departure request form
, and (6) Affidavit for DHS (both filled and signed).
我收到國泰航空寄來的不能在香港轉機的通知，國泰航空幫我
改定到五月底，
附上那封信跟後來的訂位紀錄，兩天後就收到 CBP 的通知說那個 I94 延長三十天
