If company ABC has a un-used approved labor certificate (LC) that has a PD date of 2001, and if person XYZ want to use it to file I-140, Asssuming that XYZ's skill set, experience, and degree matches the un-used LC. I understand that XYZ does NOT need to work for ABC in order to use the LC. Also XYZ has files his own LC in 2004 and now is still pending at the Back Log Eliminating Center.
My questions are 1) Will the Priority Date (PD) be the original LC PD or the date when the I-140 is files if XYZ chose to use ABC's approved LC? 2) Is it worth it to buy this un-used LC or it is better just directly apply PERM since PERM now takes much less time? 3) What about third option that still waiting for XYZ's own LC which filed in 2004?
Thanks for any ideas and suggestions!
