One of my past manager was on a O-1 (in a tech company); he was from india. So, it goes like this, you register to be a presenter in a conference, copy some material from another tech talk and (re-)present it there as a novelty (rince and repeat). Pretty Simple. Step #2, create your facebook, youtube channel (etc.) and buy subscribers (from mediamister.com, getafollower.com, views4you.com, socialwick.com, buzzoid.com, etc) which is perfectly legal; he must have spent 10% of his salary to buy millions of subscribers; and that's how he's been working in tech for the past 10+ years.

Do you have evidence this was true? This sounds like a good story but I thought getting these visas was mostly about revenue receipts, and if he bought a lot of subscribers, they must've been subscribing to something that paid him.

This is just a sad read. And probably worth an in-depth article.
