If your boyfriend entered the U.S. legally, did not leave since, and does not have any criminal convictions on his record, all you need to do is: 1) Ask yourself whether you really, truly want to be his wife (because if you change your mind sometimes in the next 3 years, it will really, truly screw up his life); 2) If the answer to the first question is "Yes", get married; and 3) Retain a competent immigration attorney and ask him/her to prepare and file the necessary papers with the Immigration (some people try to prepare the papers themselves or go to a notario or to an "immigration consultant"; most of them end up very sorry about it).
