[签证预约] H1B 上海 09/25/2008

just called two minutes ago, asked several questions:
(1) the earliest date is 09/18 and the latest is 09/25
(2) about the 09/29 and 09/30 national holiday schedule, they cannot tell because there is no any notice yet (hard to believe that....)
Any one plan to get visa on 09/29 or 09/30? or anybody know whether they will work or not on those days? Please share if possible. Thanks
