I got a letter of LC denial, today. And the reason for denial is below.

The Notice of Filing for the Application for Permanent Employment Certification was posted for fewer than 10 consecutive business days. Specifically, the employer indicated on the Notice of Filing posting dates of October 1, 2007 thru October 12, 2007. However, October 8, 2007 was a Federal holiday (Columbus Day) and non-business day. Therefore, the employer’s Notice of Filing was only posted for 9 consecutive business days.

In this case, if I appeal this, would they re-consider my case or no hope, at all?
FYI, my company doesn’t consider Columbus Day as a Holiday.
(I have a 2007 holiday list fm my company.)

And is this my lawyer’s fault?
If so, what should I do to make things work.

Please advise if anyone knows….
Thank you!
