回複：感謝8老師的回複，還有一問

我媽媽的指紋不清楚，如果指紋過不了，該怎麽辦？
-I don't have a idea, but I think this fingerprint is not strict because it is not used for background check, but for identification in producing the reentry permit document, so it may be fine to pass.

是不是象申請綠卡一樣，兩次指紋不過，就要拿police clearance letter? -Don't think it is needed.
