$30 million taxpayer money. over the next five years. that's a fraction of the budget. but to robert harrison, it's his job. >> i can't wrap my mind around training somebody to take my position. you know. this is my livelihood. how am i supposed to feel? >> reporter: i've heard some workers say that this is like digging your own grave. is that what this feels like? >> it feels worse than that. it feels like not only am i digging the grave, but i'm getting ready to stab myself into the gut and fall into the grave. >> reporter: when the visa was created in 1990, it was intended to help the u.s. attract and hold on to the best foreign graduates like engineers and scientists and provide a pathway to citizenship. at the time, members of congress promised u.s. workers would be protected. >> this legislation protects american jobs.

>> reporter: former congressman bruce morrison, then chairman of the immigration committee authored the bill. you came up with this legislation. what do you think of what it has become? >> i'm outraged. the h1b has been hijacked as the main highway to bring people from abroad and displace americans. >> reporter: businesses insist the visas are absolutely necessary to compete for the best global talent. and that even more h1b workers are needed to fill job shortages. nearly every major high-tech company, including apple, google, facebook, has employees here on h1b visas, media companies, too, including cbs. your argument is that they can't find enough qualified american workers. >> well, there are a lot of qualified american workers, but the companies will do better financially, if they hire the foreign worker rather than the american.

>> the american workers are just as skilled as you are? perhaps even more skilled? >> translator: yes, that's true. >> reporter: he works at a major wall street bank on an h1b visa. to protect his job and personal safety, he asked that we change his appearance and name. he was placed at the bank by one of the growing number of outsourcing companies. most of these global staffing firms are based in india. they've become multi-billion dollar enterprises, supplying american companies with h1b workers like him to replace american workers. he said i was never told in india he'd be taking americans' jobs. >> translator: i have to take all of their knowledge, and basically, i have to steal it. that's my job description. >> reporter: and the american worker is let go? >> translator: yeah. the american workers lose their job. and they also cry while leaving the job.

>> reporter: they cry? >> translator: i've been working there 20 years, and suddenly, i've taken their job. if i lose a job, i can go back to india, but where can they go? >> reporter: you must know that when most native-born americans see this going on they blame you. >> translator: yes, but i'm not the enemy. the main villains are the indian companies and their american corporate clients. they are exploiting us. >> reporter: why can't we just say we're going to give jobs to americans first? >> well, that's what the statute says, but. >> reporter: but? >> there's a loophole. and the loophole says if you pay over $60,000, you can do that. and beside that, you don't have to try to find americans. well, $60,000 is not high pay for this kind of work. people doing this work today easily make $120,000 to $140,000. >> reporter: who put in that loophole?

>> well, it was done by congress, but obviously, the industry lobbied for it. it's really travesty that should never have been allowed to happen. >> it wasn't called training your replacement. it was called knowledge transfer. >> reporter: craig deangelo worked for northeast utilities, now called eversource and was one of 220 i.t. workers replaced by h 1 b visa employees. he said his replacement, a worker from india, told him he was making half deangelo's salary with no benefits. >> i didn't get laid off for lack of work. i got laid off because somebody cheaper could do my job. >> reporter: to anyone who would say you're anti-immigrant. >> no. >> that's a lie. >> that's a lie. >> reporter: you don't want to have any animosity towards them. >> because they're looking for a better way of life. >> reporter: we met with this group of workers who all had to train replacements. leo perrero had just received high marks from disney, when he

was called in, he expected a raise and promotion. instead? >> i was given the news that in 90 days my job was over and i had to train my replacement. never in my life did i imagine, until this happened at disney, that i could be sitting at my desk and somebody would be flown in from another country, sit at my same desk and chair and take over what i was doing. it was the most humiliating, demoralizing thing i've ever gone through in my life. >> reporter: the issue was getting little notice until it caught the attention of the trump campaign. >> love you. thank you. >> reporter: mr. trump himself had hired foreign fashion models on h 1 b visas for his new york modeling agency. but when he saw how the theme of protecting american jobs resonated with his followers, he put sarah blackwell and fired

workers like leo perrero on center stage. >> there's two reasons, two words of why this is happening. corporate greed. >> reporter: attacking the h 1 b visa program fit perfectly with mr. trump's message and tapped into america's simmering anger at the corporate and political status quo. to watch the full report go to cbs news.com and click on "60 minutes". we'll be right back. ok, let's try this. it says you apply the blue one to me. here? no. have a little fun together, or a lot. k-y yours and mine. two sensations that work together, so you can play together.
