You may have a variety of options available to you. A relative may be able to sponsor you or, if you find employment in a Specialty Occupation (a position that requires at least a bachelor degree in a specific field) related to your area of study, your US employer could submit an H-1B petition on your behalf. There are still roughly 20,000 cap-subject H-1B numbers available for a start date on or after October 1, 2009. Without more specific details regarding your family connections and job opportunities in the US, it is hard to offer concrete advice. You should consult with a qualified US immigration attorney to explore the options that may be available to you.
