拿着中国护照。
听说可以在机场海关申请L1，不用去大使馆吗？
-Because you are not Canadian citizen, you can not do that. You must go outside US to get the L1 visa or change your status to L1 within US through your employer's filing of I-129 for L1 petition.
能否先拿H-4来美国，然后带着L1申请的材料去机场海关？
-No, but you can change H4 to L1 in US.
还要请律师吗？
-Talk to your employer and this is your employer's bussiness, not you.
不知大概有多少费用？
