Some of my friends came to US on J1 and converted into H1B.  According to them it is not that difficult as people say. The only rate limiting factor I see is J1-waiver by Nepali Embassy, because Nepali ma ukhan 6 ni "Rajako kaam kahile jala ghaam". Bottom line, don't worry buddy, majale aaye hunchha, mera dherai saathi harule tesai gareka chhan.

Hope that helps
