The article doesn't back up your claim.

People in the US on H1B visas don't have their passport taken away and are prevented from leaving. They aren't arrested and imprisoned when they are gang raped. They aren't forced to live in shanty towns with limited facilities like running water. They aren't working 12 hours shifts 6 days a week. They aren't earning $580 a month (the $70k a year the article complains about is at or above the median wage in the bay area). Here in the US we also don't have laws on the books punishing homosexuality with imprisonment and death.
