I don't know what job postings you are seeing but the vast majority of Data Scientist/ML Engineer postings at large tech companies that I've seen explicitly mention Statistics as a requisite skill.
Sure, and most of time they do not vet the candidate during the interview. Even if they do, they ask basic questions about normal distributions and other basic concepts.
I feel like the number of tech people who legitimately worry about their spouse being deported is extremely small. And it's only two years until the next election anyways.
It will be really interesting to see how the community reacts when they revoke H4-EADs. It is one thing that you did not had ability to work for years and then you did and suddenly you don't.
For high skilled people it can be I know a CTO who moved back to the uk from the valley mainly because his wife could not work - she was a senior nurse I recall.
Well your initial point was that people will put up with Canada's cold winters to avoid having their spouse deported. I don't think that is a realistic scenario (and if your spouse is an illegal immigrant, I seriously doubt Canada would let the immigrate).
It is sad that many people who are sympathizing with this legal immigration issue, fail to realize that it was not all hunky dory for high skilled legal immigrants (HSLI) before Trump started.
FWIW, HSLIs especially from India are suffering because of policies by Clinton/Bush/Obama administrations.
Trump administration just ensured that every rule is followed to the T.
This may sound sadistic, but I'm glad Trump administration is doing this, because immigrants and employers will start feeling the heat of these insane rules, and finally it may lead to a sensible legal immigration reform. Had it not been for Trump, you'd have more than 95% of those HSLI waiting for Green Cards not utter a thing against the rules from the previous administrations.
Getting deported is not the issue. Problem is that every single day you wake up to this uncertainty that you may get deported, but you are not sure. And being a legal immigrant who broke no rules, adds to that frustration, of being treated like an unwanted immigrant in a country that most people are blissfully unaware of.
They sure have strong opinions about working on Government projects but none of them have any issues creating tech that intrusively monitors and manipulates people for the purposes of serving them advertisements. What heroes they are...
