婚姻綠卡Request for Applicatnt to Appear for Initial Interview, 請問：

麵試通知單有一個 很長的check list, 其中一項是：

A completed Affidavit of Support (Form I-864) with all required evidence, including the following (unless already submitted):
  - Federal Income Tax returns and W-2s
  - Letters from each currents employer, verifying current rate of pay and average weekly hours, and pay stubs for the past 2 months;

當初交申請表的時候已經交了Form I-864, tax return, W2. 當時表格沒有要求employer letter, pay stubs 等等，現在麵試需要預備這些材料嗎？

一般這樣的麵試是夫妻分開麵試嗎？如果麵試沒有問題，是否等於綠卡批了？

謝謝！
