Have you considered any other visa options to obtain US residency? Do you have no work experience, so the EB3 visa from the other workers category is the only one that suits you? Because I have exactly the same situation and, by the way, I only started working with EB3 visa companies a month ago. First, I advise you to read the EB-3 recruitment transparency guide on the eb3.work website, which explains in detail what these companies are and how to choose them best. In simple words, these are recruiting companies that look for affordable employment options for you and help you throughout this process. Are you planning to look for such a company? I can tell you about mine and maybe it will suit you too in all conditions.
