5/13寄出材料，5/24收到email说已经批了，可是到现在还没有收到护照。买的是USPS
priority的回邮信封，usps网上查询tracking number,结果是not found. 写信去大使
馆问，他们说：
Please note that your passport and documentation could still take some time
to reach you whilst being sent back from the decision making centre and
whilst other administrative formalities are completed. The visa application
centre will be in contact with you regarding the collection or delivery
including your tracker number.
有人碰到过类似情况吗，现在就是不懂他们到底是寄没寄出来。可恨的是在邮局买回邮
的时候，那个人粗心把我的回邮receipt丢到大垃圾桶里去了，我付完钱问她要
tracking number，她在桶里挖了半天给我一个小标签，也不确定是不是对的。
