兩個人都是10年B1/B2 Visa，目前要申請延期才發現I-94上一個B1，一個B2，這種情況下，能一起申請延期嗎？就是一個人填寫I-539，另一個人填寫I-539A，這樣的話，郵寄交一份申請費$370就可以了。
-No. B1 and B2 status are different, so they cannot apply for the extension in one I-539, and have to file the I-539, respectively.
我看I-539的Instruction寫的是：
You may include your spouse and your unmarried children under 21 years of age as co-applicants in your application for the same extension or change of status, but only if you are all now in the same status or they are all in derivative status.
想問問B1、B2是不是derivative status？
多謝8老師了！
