>They spend far more money and time upfront getting the person the visa and in the end there is nothing preventing them from either going home or tranfering to a similar role at another company. So if there was a law that said they can't go home or change jobs, then you would accept that it might be worth it? But if that were the case there's still nothing preventing them from dying right? Hopefully from this example you can see that an employee who is much more likely to stay for x years, is more valuable despite the fact that they aren't guaranteed to stay for x years. If you could pay $30k extra for an employee that is 50% more likely to stick around for 5 years, most companies would jump at that chance.
