回複：I-485 to have Biometrics taken

我的ＣＡＳＥ跟您的很相似，也是ＮＳＣ，也是２００２年十月ＦＩＬＥ的Ｉ４８５，是ＥＢ３。也是按了兩次手印。現在收到Ｉ７９７Ｃ要做biometrics。是ＣＯＤＥ　２。我問了我的律師。這是他的答複：

Code 2 is to check birth date/country and parentage. Applicants are required to go through this before approval of green card, at times, even after approval but before issue of actual card. I believe your case will be approved soon after the code 2 fingerprinting and security name check.

我理解ＣＯＤＥ　２是thumbprint, digital photo, and signature.　祝您（也祝自己）好運。
