Regarding your first question, you would get a 60-day grace period following the end of your employment (limited, however, by your I-94 expiration date). During this 60-day period, you could remain in the U.S. and apply to change your status to another visa classification before the end of the 60-day period, such as to another work visa (if one is available) or a visitor visa. Regarding your second question, you are referring to an EB5 green card. That is too convoluted to explain here. If you are interested, you should consult with someone who specializes in EB5 green cards.
