Thank you for everyone who responded.
I tried to figure out the chances that the Embassy may update the list this month. Here what I came up with. The Embassy, according to their website (
http://cairo.usembassy.gov/consular/iv8.htm ), has scheduled about 40 interviews per day up until June 10. And roughly about 18 interviews thereafter i.e. from 6/11 to 6/30. This means they average about 40 interviews/day. Therefore, it's more than likely they will update the list with more June dates to bring the daily quata to 40.
I don't know whether this make sense to you or not. But I tried to bring some sense to this senseless process;: waiting for an interview!
By the way, I did email the embassy requesting to update their interview list days ago. Still waiting.
