Thanks guys for you input...
Ya it's been 3 years I filled i485.. No not much worried about greencard( which will take few more years PD to be current  ). but my major concern is about EAD while moving to new company.

few question of the top of my head are:
DO I have to worry about that the desi company will notify uscis?
can I easily renew EAD from new comapny?
what should I tell new company about work permit?

any suggestion is appriciated !

thanks,
