If you expect that the documents have been or will be delivered soon, please allow sufficient processing time for the documents to be delivered to our office and updated on your Applicant Status page.  lease contact us again through our "Help?" page (http://www.wes.org/contact.asp) with the tracking information for the delivery of your documents to our office if you can provide it.
p.s.:昨天在yahoo看到新闻“cuts first class mail slow delivery 2012”,没仔细阅读只扫了一眼,今天中午在ccav午间新闻也播放美国邮政局要削减开支,在2012年度开始,国内通过邮政系统的信件筛选递送的时间会减慢,也会关闭一些服务点。但dhl,ups及fedex等自营快递公司不受影响。不知道first class delivery应该怎么翻译?和priority mail的区别在哪里?
