CD,
I wrote all my stuff in another posting(sub: I AM ON CLOUD NINE) thats the reason I did not give my details, but they are,
RD 02 July 01, ND 06 August 01. My first EAD was to expire on 15 August 02, I did not want to take any chances and applied for renewal in May 02. Got the EAD approval by the end of June.
I dont know when your first EAD expires. I would say to have a peace of mind go head and apply for a renewal.
Cheers
Kalyan
