I got Receipt Notice Dates of Nov 6, 06 for both the I-140 & I-485. But in the USCIS website, the latest dates for these are Dec 26, 06 and Mar 03, 07. I called their number but all I got was an automated message giving me the latest update on my applications saying they are pending. The date has already exceeded by more than 30 days. Is this the usual thing that happens with USCIS?
