拿著中國護照。
聽說可以在機場海關申請L1，不用去大使館嗎？
-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來美國，然後帶著L1申請的材料去機場海關？
-No, but you can change H4 to L1 in US.
還要請律師嗎？
-Talk to your employer and this is your employer's bussiness, not you.
不知大概有多少費用？
