My Sponsor/employer is worried about the documents and process if my Number is picked in H1b lottory

Hi guys,

I found a company to sponsor me for 2018 H1b. My attorney has already filed LCA to DOL. Since the company is not familier with H1b process, they are worried even if my number is selected for upcoming H1b lottery. Someone said them that the process after the lottery is complicated and now they want not to file H1b. Can you please lete me know the process what they sould do after i get selected.
