7th year extension petition with post date processing

[vijayavelp]

My employer has applied Perm Labor and my priority date is Aug 31, 2012. I have received an audit, employer responded and still waiting for the response. My sixth year is completed on Apr 27, 2013, so I left the USA on the same day starting working from India after that.

 

As per current  PERM auditing queue and my case will take at least another 2 to 3 months. After approval I need to go for I-140 approval to get 3 year extension.

 

In this situation, can I apply one year H1B extension since my 365 days will get over in Aug 31, 2013?

 

If it is possible, can I apply one year H1B extension with post date of September 1, 2013 in the application and start premium processing now itself so that I can return in USA in September? 

 

Please advice on this and thanks in advance.
