What is the easiest and fastest way to work in US without complicated procedures?

The ways by which a foreign national may travel to the U.S. to become a Permanent Resident and then later apply to become a naturalized U.S. citizen generally fall in to employment-based visas, family-based visa, asylum and refugee visas and investor visas. Each potential avenue has extensive requirements dictated by statutes, court decisions and regulations. There is no single answer to "what is the easiest and fastest way," since that analysis will require extensive information about the applicant's qualifications in the appropriate visa category. If you may believe that one of these avenues might be a good "fit" for you, then it would be wise to consult with an immigration attorney who could learn all of the relevant details about you (and about your proposed employment, your family relationship, your proposed investment, etc.) in order to advise you about eligibilities, options and strategies to meet your goals.

There is no such a way. All work visas or almost all visas require either outstanding ability or a petitioning employer. In any event, the process is costly and sometimes lengthy.
