approved I-140 status changed to initial review

[Ramya_K]

My I-140 approved in 2009 & now USCIS changes its status to initial review.

 

Do you guys have any idea why they changed status to initial review for existing approved I-140?

 

If employer apply for my I-140 revoke then is it goes to initial review?

 

 

Thank you,

Ramya
