Hey Clupen.. its entirely up to ur luck.. I went through with the same thing 3 years back and I even had related academic background. My H1 petition was approved by USCIS and still the US consulate in Nepal revoked my petition... I believe it was because my Indian consultation was unable to provide all necessary information requested by the consulate office. But I dont regret it much coz I came to US the next year on Student visa..
