请教各位过来的人，PERM过程中，这个in house media posting和employre website
advertisement有啥区别啊。
律师列出的东西，我怎么看不明白啊
In-house Media Posting: In-house job notice for ten (10) consecutive
business days (must be published in all the company’s in-house media, both
print and electronic, such as the company’s website)
这个东西和后面将要采取的employer website的广告有啥实质区别吗？
如果是同一样的，又何必分成两步呢？
