EAD on EB2 , Apply EB1 ?

[rabindra_das]

Hi

I got my EAD on EB2 with I-485 application. Its been 4 years. Now I see EB2 date has been set back to 2006.

I am going to join a new company as Manager or equiv.

My question is ,
1. can I apply the GC on EB1 again if I qualify ?
2. Will there be any problem to current EAD if the EB1 is denied ?

Appreciate your response .

Thanks
Rabi
