summit,

thanks for your response. But when i open website you refer, it prompts with warning. I wonder only employer or attorney can only access this website. I will try to get reply from my employer. on the meanwhile, waiting is the only option I have. my consultancey(employer) applied Labor certification for me. Some employee already got approval and some on the way.  By the way I am working with them for 1 year.But I don't know whether they have advertised for the post or not?
