Many international universities have an international department that will help you find grants or loans to finance your studies abroad. Also check with your country or local municipalities if they have ways to support your dream come true.
Good sources are Embassies and consulates, chamber of commerce and other institutions that promote the international exchange. Sometimes a google search will give you additional ideas.
I have helped hundreds of internationale students to full fill their dream of studying in California. One thing I hear over and over is, that they believe it was worth every dollar they spent. They truly got an international education and experience that they will cherish their whole life.
