Thanks teacher 8 gain.

     Then I must mixed up between it and Laber certificate for i140.

    Last quesition, how long does it take to get LCA and how hard to apply it (I read it can be done online iCERT, and takes about 7 days). But what is needed before filing (e.g., need advertisement)?

Thanks Again.
