Urgent Help Required - No AOS/EOS/COS

[mathranik]

Hello everyone! I am posting this query in a state of panic.
My parents came to the US on the 5th of March 2010, and were given a 6-month stay period. The stay expires on the 1st of September. Now, in the mid of july, my parents visited Canada and came back on the 23rd of July to US. When they came back, their I-94 was reissued, and on the backside of I-94 under the 'record of changes' section, the immigration office wrote with hand- 'NO AOS/EOS/COS'.
Not knowing about it, I applied for their extension of stay on the 3rd of August'2010. Today I came across the remarks on their I-94. and began to panic. I called USCIS, but they didn't have much information about it at all. They asked me to make an infopass appointment.
I would like to know from all of you people how to go about it. What does it mean, if it says this under the 'record of changes' section.
Thanks a lot in advance.

Forget the extension application and have them leave before their I-94 expires. The sooner they leave the better.

I wanted to add to my previous post that, half an hour ago, I got the receipt from USCIS confirming that they have started processing the application. It has come 10 days from the date of filing. Isn't that swifter than usual?

Also, I read elsewhere in this forum and another one that, since the person who has filed for extension doesn't go out of status even after expiry of I-94 until he receives a reply to the extension, he/she can stay beyond the expiry of I-94. But I also read that if the extension is denied, it jeapordizes the re-entry of the same person in US the next time. (Although a denial in extension of visa doesn't mean cancellation of a multiple entry visa). Correct me if I am wrong.

What is the reason for the extension?
