H1B case status, pp 和non-pp 的最终状态不一样吗？

我了解的 对于non-pp, 最终状态是case was approved。如果是pp的话，会有个状态是case was approved and my decision was email, 但最后好像不会再变成case was approved了。是这样吗？

在看同一段号的case，想知道怎么区分pp 和non-pp。

如果receipt或者decision 是email通知的都是pp，否则都是mail的

有“my decision was emailed”是pp，只是“case was approved”是non-pp

根据我的统计，看到case was approved and my decision was emailed可以确定是pp，但看到case was approved也可能是pp

我自己前几天的pp的状态是先变成decision was mailed, 再变成decision was emailed. decision was emailed approve之前的最后一个状态。
