正在准备I-485面试， CIS的通知上面在you muct bring the following items with you一栏中有一项是：A completed Affidavit(s) of Support(Form I-864) with all required evidence, including the following, for each of your Sponsors (unless already submitted):
-Federal Income Tax returns and W-2's, or certified IRS printouts, for the most recent tax year,
-Letters from each current employer, verifying current rate of pay and average weekly hours, and pay stubs for the past 2 months,
-Evidence of your sponsor's and/or co-sponsor's United States Citizenship or Lawful Permanent Resident Status.
我在网上查了一下，都说Employment Based 的绿卡申请不需要填Form I-864，可信上有说要，到底需不需要准备？
还有就是他要most rencent year 的tax return，但我面试是1月15日，到那时我公司还没有给我2009的W-2，给2008年的行吗？
最后就是Evidence of your sponsor's and/or co-sponsor's United States Citizenship or Lawful Permanent Resident Status. 实在搞不懂，我的绿卡是公司给我sponsor的，我找谁要Evidence of your sponsor's and/or co-sponsor's United States Citizenship or Lawful Permanent Resident Status？
都快给弄昏了，一直以来在这个坛子上得到各位大侠很多帮助，希望这次也能为我释疑解惑，多谢各位，在线等！
