gingibi,
You are right, I have old address when I applied my AP.
But, don't they check there system for the right and latest address before sending the approvals.
Thank god, it went to attorney, otherwise It could have gone back to INS as undeliverable and I would have been in infinte loop to get my AP back.
I guess AP approval goes to attorney and 485 approval to applicant. Now I am worried about my address on I-485 application.
