There are as many as 1.5 MILLION visa workers here in the H1B PIPELINE. The vast majority are ALREADY IN THE US and will be un-affected by this new rule.
And another 3 MILLION ex-H1Bs - who have been given "-American" citizenship. Who will be wholly unaffected.
Why does this matter?
These are the bulk of the population who somehow keep hiring other H1Bs (or ex-H1Bs) - rather than Americans, even though they are now (typically Indian)"-Americans".
So this new rule will not result in them hiring Americans instead of H1Bs and ex-H1Bs, and therefore not work for all the Newly Un(der)employed Americans (over 1 million) tossed out of Tech by the H1Bs 2022-____ (on the pretense of "AI" but in proof, simply replaced).
This new rule only applies to (typically) NEW H1Bs NOW OUTSIDE THE COUNTRY. But again, the vast majority of H1Bs are already in the country.
Finally, H1B-Dependents are EXEMPT from this new rule - and both annually and in total there are now MORE H1B DEPENDENTS THAN EVEN H1Bs (it's Chain Migration - by an Obama Executive Order that Trump refuses to end).
So - in sum - there will be A LOT OF NOISE about what in the end are a few 10s of 1,000s of people who won't make it to the US before the deadline given with this announcement. The result? We have to wait and see, but if Trump hopes to hit 50,000 H1Bs for the $100,000 fee on the way in (and gets it) that's only $5 billion -and so would not even scratch the Deficit.
And that's before we start seeing Trump carve out "Exemptions" (I hear they are already agreed to, but we are awaiting details), and then court challenges (which Trump's lawyers know may mean this is all anyway just one big show that - as small as it is, will not stick).
