LCA posting means that your employer posts LCA on publicly visible areas in your office. LCA certification is applying for LCA approval with the Department of Labor (DOL). In cases of the H1B Amendment, you need a certified LCA whereas, in case of changing working location within the same MSA where no amendment is required, you can only do LCA posting. LCA can be posted at either your home or at the employer headquarters building if you are working from home on a work visa. Recently, DOL made it mandatory to mention your end client name on LCA to avoid denials.
