我这个礼拜从上海出关，问了一下这些问题。 出入境说，入外籍的要退籍，退籍的流程包括户口注销。至于户口是否已经注销，没注销在哪里，都要本人自己搞。
Once again，new rules are about to be implemented, on a group of people who are not even their subjects anymore, without clarity and without any due process. I suspect this is done so that they can selectively enforce the rules.
