PD Current in Dec 2011 - Pending 140

[nandkri]

Hello friends,

Please suggest on my situation

I have a approved 140 from Company A with PD of Dec 2007

I changed job this year and with new company, I have approved labor May 2011 and filed for I 140 requesting for porting previous PD

My 140 receipt still shows PD as May 2011 and not Dec 2007. Will PD portability happens only on 140 approval?

Will I be eligible for concurrent filing next month?

Is it better to change 140 to premium processing to get decision by next month?

Thanks
