These faux "geniuses" who are supposedly essential to our tech industry can't figure our their own work permit! How friggin' stupid that be!
You left out important information.
H-1Bs are typically renewable for six years.
Then, if your employer agrees to sponsor you for a Green Card, you can remain in the USA indefinitely until your Green Card is issued, or until you have exhausted all the hearings and appeals that are available if your Green Card is denied.
At least half of H-1Bs apply for Green Cards, which means an H-1B visa can easily stretch out to 8 or 9 years.
Part II
I forgot to mention that many H-1Bs start out with OPT Student Work Visas, which renew for 36 months.
Almost all the OPTs and H-1Bs have completely “average” skills.
They crush the wage scale for completely “average” American STEM graduates, and for “average” American scientists and engineers over age 40.
