I keep reading this kind of articles from many Nepalese living in US. From one point of view, their outcry is justified; they invested over 10 years of their precious time, got away from their family and took huge loan to come and study in US. But what do they have to show for themselves? A job in consultancy that didn’t require any of those things?
My few cents:

1. USA or any US institutions (unless it’s one of those fraudulent for-profit colleges) never requested you to come over here and guaranteed a return. Hope is one thing, expectation is different. Even if you finish your doctorate with honors you aren’t entitled to anything.
2. Be happy you are getting a consultancy gig. Think of what would have happened to thousands of Nepalis living in US had it not been those consultancies and their resume-padding ways.
3. With proper education, you can make consultancy just an entry foyer – then it is up to you to expand your potential.
4. No, consultancy is not the only thing Nepalis in US are employed in. Yes, a huge chunk are – but few are employed in other well rewarding ventures.
5. You said you took a huge loan. Unless you took a loan to send back home, I am not hearing it. I came here with minimum amount in my pocket. I went to State universities that had lowest cost and I worked day and night to fund my education. I didn’t spend time partying or thinking there’s loan to take care of my education. So stop crying about the loan – you chose it – it wasn’t your desperation.
6. Be happy with what you have and strive for more. Your education allows you to expand your horizon. Remember, gig in IT might be short lived, treat it as a temp stop until you find something you like. Unless of course you want to make IT your career, which can be equally rewarding as well.
