I have a 15 year-old son, who is taking the second year for his senior high school in mainland China. Wondering the possibility of sending him to the U.S. for high school education so that he can continue on for college education in the U.S., is there anybody who has done this or has come to the U.S. at high school level with F-1? Could you please let me know how I should start and where I can find some information about the high schools in the U.S.?
