validity of first EAD in case of 2nd 485 filing

[gcApplicant1234]

Hi,

First of all hats off to moderates. Great forum.

Here is my story:

I currently have employment based 485 pending in EB3 India Category, I am working using EAD. My wife is also working on H1 (She does not have 485 pending/ EAD since we got married after I filed 485 in 2007 when it was current).

She recently started her EB1 petition and we are thinking to file 485 for me as well since EB1 is current and EB3 moves only one week per month at Max (my PD is Dec 2002 BTW).

I know that I can not have two 485 and I will have to withdraw my earlier 485. My question is what will happen to my current EAD ? will that be valid ? can i still work ? what is my legal status in US ? will i have to switch to H4 and wait for new EAD (thru EB1 485 ) to come before i can start working again ? Also is it even worth to go thru this effort considering my EB3 PD is not that far.

Sorry for asking too many questions.

Thanks for help.
