白老师，大概两月前我请教过一个关于我父母绿卡登陆的问题，（相关帖子https://bbs.wenxuecity.com/immigration/621606.html） 。
象我帖子里所述，我母亲已经早早拿到绿卡, 按规定，她的登录时间是下月初。而我父亲上次重新提交 的Civil Document的审核在近两个月的等待后前天终于也等来了结果，但很不幸，再次被打回来了，打回来的原因仍然是不可解的："Part of this document is missing or is difficult to read. Please replace this with a scan that shows the complete text of the document. Please ensure all sides of EVERY PAGE are scanned and visible. Please visit https://nvc.state.gov/scan for further guidance.”. 这已经是他在这一步骤的第四次被打回，我们已经确实不知道该如何Fix this problem了。
-t seems your scanner does not work well and thus, the scanned documents were difficult to read. You may need to find a good scanner to do it again. Check the scanned dcouments to make sure the dcouments is clear to read before upload them to NVC.
但这是另一个话题，我今天想咨询的是这个：
尽管现在他的绿卡申请卡在上面那一步， 但我爸想跟我妈这回一起携行的意愿非常强烈。他们现在都是加拿大公民，这回来我这儿大概就呆个一两个月吧，理论上持加拿大护照来美是自由出入的，但因现在他所处时机比较特殊，我还是想确定一下在他的正在审核的绿卡申请窗口里来，
a) 会对他进入美国海关有什么影响吗，
-It is possible he has a problem to enter US due to immigrant intent. But not hurt him to try.
b) 或者对他的进一步绿卡申请有影响吗-No.
c) 有什么需要注意什么吗-He needs to convince the officer at the port of entry that he will return to Canada after shortly visiting US and then, apply for the immigrant visa in Canada if the officer asks his immigration case.
谢谢白老师
