And I'm sure that he agrees with you now. Recall that the guy moved his wife with him halfway across the globe to Vancouver to get the job, and has to move all the way back again now that he has left it (because of work visa limitations). If you think he didn't spend sleepless nights thinking through the consequences, you're (probably) mistaken.

Hindsight is 20/20. The opportunity to make a FAANG salary, even if it requires putting in some time at the lower ranks, is not one to be turned down lightly.

The average computer engineering salary in Tel Aviv is somewhere around $85-95k, before (high) taxes, in a city which is the 9th most expensive city on the planet in cost of living, supposedly more expensive than New York. Level aside, $110k guaranteed, before lucrative RSUs, (I presume) lower taxes, lower cost of living... should speak for itself.

So then you do it like we used to back in the day, where we do our time (at least one year) while you look for a different job. Then your visa does transfer over. Choosing to leave before the one year is up is his fault, too.
