Xiaobaitu: Please help with this EAD question

Xiaobaitu,

Currently I am holding H1 and my 485 ( I am the primary petitioner of this NIW) is pending. I am planing to use my EAD to do a second job ( full time or part time, not related to my NIW research work). My question is:

1. As the primary petitioner can I use EAD to do unrelated work ( I'll keep the the current NIW research job)?
1. if I still keep the current research job, does this second job hurts my 485?
2. once I use EAD, can I still have this H1 ?

Thank you very much and have a nice weekend.
