H1B processing

I am looking for job opportunities through H1B filing for US opening, however the consulting firm is asking for 3000$ visa processing. In case if it is rejected they will pay me back 1500$. Is it safe to file H1B?

Opulentsoft is the consulting firm. Is it fake or geniune?

First of all, paying for H-1 is illegal.

So if you don’t make through the lottery, company makes easy 1500. How do you ensure that your petition is really filed?

If the petition is selected but denied due to reasons related to the company and not you, what do you get back?
