Could it be that you have not adapted your resume/cover letters and so forth to the American market? There are regional differences between what should/shouldn't be included in a resume, like a picture of yourself, your age, your family status and similar things. A resume not tuned for the local market may disqualify from some positions in the hiring manager's mind. Finding a job in a new city is never easy but a capable programmer has a better chance than most others! Have you tried any visiting any local meetups, conferences or co-working spaces?
