回複：應 該 是 人 在 美 國 時 申 請 ﹐ 否 則 可 以 拒 你 的 AP

Understood. But how to define presence in US? meaning that i need to be present when I drop the file to mail or be present to obtain the receipt? Even if I decide to come back for this purpose, but how to manage the timing? Please help with my dilemma. Thanks.
