There are visas for this. E-2 non-immigrant visa, for treaty investor visa, renewed every year. EB-5 permanent resident visa, for investors who invest 1 million and create 10 jobs or invest 500k and create 5 jobs in economical hardship area (I guess such as Detroit?) No special visa for penniless entrepreneurs though.
