关于PP处理时间的一点疑惑

[align="left"]邮件里说[/align][align="left"]The California Service Center will adjudicate this case within15 calendar days of the "received date" set forth above.If approved, you will receive e-mail notification of such.[/align][align="left"]然后 received date 是 04/13/2015. 那意思是04/28之前有消息吗？[/align][align="left"]但是, USCIS 官网上不是说, they would begin premium processing for H-1B cap cases on April 27. [/align][align="left"]所以...15calendar days从哪一天开始算呢？[/align]
