I485 infopass 預約準備神馬問題

最近看了些印度哥哥的貼子，我也預約一個 infopass appointment( http://www.immihelp.com/immigration/infopass.html ). 小弟我的基本情況：

   1. EAD/AP received Mar 2nd/2012;

   2. PD 2008/07/29; RD 2012/01/18

我準備了幾個問題（參照了皮匠大俠的寶典）：

 1。 Has my I-485 application assigned to an immigration officer ( or visa officer );

 2. My namecheck( background check ) cleared;

 3. Roughly when I can get my I-485 approval.

 各位大哥大姐們，還有神馬問題我需要準備？去一趟也不容易哈。預祝各位大哥大姐綠卡路上少些顛簸，小弟我這廂有禮了。
