最近收到Welcome Notice, Approval Notice及绿卡。我依然有如下问题。请Pijiang老师和各位大侠答疑解惑。
1. 在绿卡上有Category: E37. 在Welcome Notice上有COA: E37.请各位解释其含义。
2. Welcome Notice I-797C
我收到的Welcome Notice是 I-797C. 我的Welcome Notice是Courtesy Copy. 原件寄给我公司的律师了。在Welcome Notice上有如下说明让我担忧。根据法律，谁应该保存Original Welcome Notice呢？是公司？还是我？如果公司应保存Original Welcome Notice，我是否该有其复印件？
“This courtesy copy may not be used in lieu of official notification to demonstrate the filing or processing action taken on this case.”
另外，Welcome Notice上有：" The official notice has been mailed to the attorney. Any relevant documentation included in the notice was also mailed as part of the official notice”. 除了Welcome Notice难道还另有relevant documentation？
3. Approval Notice 是否就是Form I-797D?
我随绿卡收到了Form I-797D. 绿卡是插在硬的纸片Form I-797D上。上面说” Your Application Has Been Approved. 是否Approval Notice就是此Form I-797D？还是另外还有一份Approval Notice？
4. 将来万一绿卡遗失或过期，什么文件可证明身份？Welcome Notice 还是Approval Notice？还是二者都要？
谢谢各位！！
