ABHIJIT,
Thanks for adding to the tracker. And your information is useful. We also received the notice and never knew the EAC# should be changing. Now I can track them in the web.
Also, we filed change of address during the I-90 application and the notice was sent to our new address. We had no problems, whatsoever.
Thanks!
JLCF
