現在申請美國親屬移民的人是越來越多，無數人盼星星盼月亮就是爲了那“一紙”綠卡，但是在申請過程中他們卻會遇到很多問題，小編最近收到不少朋友的疑問：美國親屬移民的P1、P2、P3、P4都是些啥?其實也不能怪這些朋友不了解，事實上美國親屬移民中的其它名詞如F1、F2A、F2B……也同樣很容易讓人疑惑，畢竟這些簡單的縮寫對于沒怎麽接觸過的人來說確實是一頭霧水。好了，閑話不再多說，下面進入正題。
【P1階段】
所謂P1階段就是當大家申請美國親屬移民時，先假設申請人是A，A將申請資料准備齊全，然後遞交美國親屬申請表I-130至美國當地的移民處理中心，接著A就會拿到檔案號碼P1,也就是我們通常所說的表I-130申請收據。檔案號碼P1裏面包含有三個英文大寫字母加10個數字,三個英文字母分別是EAC或WAC或SRC或LIN,分別對于不同的美國移民處理中心。下面小編給大家看一下P1的樣本，讓大家對P1有個更全面的認識。
