H1-B transfer/extension in 7th year while Labor pending

[H1bboat]

My PD is Jan 2013
current status:Audit
I am currenlty in 6th year and my H1 is valid till Feb2014.
I am looking for advice/guidance from experts on same questions

1.Will I be able to change employer at this point of time, Can a new emp apply my H1 Extn/transfer considering that I have applied for GC before 1 yr term with the previous employer..

2.I am looking for options incase my labor is not approved after audit.

3.If I get 7th year extension approval with current employer, Can i transfer to new employer to apply for new perm incase current perm with current employer not approved

Please guide me the options

Thanks in advance
