prevailing wage determination times

Does anyone have the updated timelines for PWD ?

I applied 9141 on 14th Dec 2017 and its been past 60 days.

Is there a way we can check the status of the PWD application?
I'm from Nepal and I applied for asylum in 2015- no interview yet. I also got TPS and now my employer is applying for my green card and I've started the perm process. When do I retract the asylum application? Now or wait till I get my EAD/green card ?
