1.“the copy of your spouse L-1 approval notice”,是指I-129么?
-No. That is the approval notice including the I-94 for your I-129 application.
请问I-129是提供原件还是copy？
-Not need I-129
我是自己带129回去延期L-1再回美国，回来后办L2延期
-What do you mean? Do you say your a Canadian citizen and get the L-1 at the border? If so, provide all the documents about your L-1 approval you get at the border such as L-1 I-94, etc.
2.老婆和孩子用一个I-539 File，交钱是交双份还是一份？貌似Instuction上没写
-One filing fee is enough.
3.为什么需要配偶3个月的paycheck呢？
-This is the proof that you are still working (L-1 is valid). If you lose job, your L-1 is invalid and thus, your spouse and kid can not extend their L-2.
4.L-2的护照和I-94需要交原件一起邮寄过去么？
-Copies of L-1 and L-2 I-94s are OK.
