L-1的右下角工作许可时间范围有个过期日，比如说是01/2012；但是2011年3月份入境I-94给到03/2014， 那是否代表着只能工作到01/2012，但是可以居住至03/2014？
-It is unusual for the CBP officer to issue the I-94 duration longer than the L-1 approval notice. Normally the I-94 you got should have the same duation as your L-1 approval notice duration. Technically, you can stay in US until the I-94 expires, but probably you can not work after the approval notice expires (I am not very sure this), so, you may ask your employer to file I-129 L-1 extension petition for you before the approval notice expires, and your wife and kid may also extend their status with you, and I think this is the safest way for you to do. Your wife and kid's status duration can not longer than yours (only can be either the same as yours or shorter than yours), and that is for sure.
Anyway,you may consult a lawyer for more suggestions.
还是表示I-94的03/2014是错误的，应该只给到01/2012？ 家属的给的时间更长，是否也表示都应该只给到01/2012？
