我現在美國工作，下星期回國出差，需要在中國申請簽證，在網上填新的DS-160表。填完後，提示需要帶好的材料是：
護照；經核準的I-129證明。
請問這個核準是什麽意思啊？
-It means the H1 approval notice. You can get it from your HR or just photocopy it.
我從工作單位複印了一份I-129，行嗎？
-You also need that copy of I-129 with the LCA approval and the employment verfication letter from your employer for the h1 visa application.
