Well intentioned but misses the mark. If this had been in place when I came to the US, me and many of my friends (petroleum, chemical, electrical and software engineers and possibly nurses, doctors, anesthesiologists and doctors) would have had to have left the US after getting STEM degrees here. Instead of this, just ban skilled immigration to the US and be upfront about not wanting immigrant skilled labor. Everyone will understand. It's your country. However, if you want to fix the problem, however, let h1b workers move companies as freely as green card holders without having to "transfer" the visa from company to company, and let holders apply for a green card on their own after a year or two. Simple. Solves the supply problem and balances the relationship between the employer and h1b holder to more closely match a normal employment relationship, not one where they hold all the cards and can literally decide your fate at a moments notice, forcing you to work for lower wages just so they can maybe .. eventually ... sponsor your green card or make you do more work than you should for the same reason.
