I think there was a shady underground way to match illegal immigrants with SSNs. Or they just networked heavily in their communities.
There are companies that provide a LLC with a SSN for just a fix payment of $400, but I am sure it comes with a lot of taxes issues that I don't want to care for now.
So, how can the financial system rely on SSN if they can be sold for inmigrants?
(Employers are supposed to verify ID too, but they're not scrutinized as heavily as a major bank like Chase.)
IIRC banks need a ITIN or SSN + passport or ID of the UBO
Undocumented immigrants are far more likely to go the... undocumented route.
In terms of immigration, undocumented typically means you don't currently have a valid visa or residency permit. In that case no, they would still be undocumented, since the ITIN doesn't grant them either.
This has to be a TIN (Tax Identification Number) not a SSN (Social Security Number). As far as I know SSNs are only issued to people.
Likewise I want them to get licenses if they can pass the driving laws test, and should be able to get insurance. I don't want to be hit (or hit and run) by an uninsured driver.
They and their kids should be getting the same vaccines someone with a legal right to live here does, under the same terms. This is basic public health that helps everybody.
This is 100% orthogonal to whether ICE should be pursuing and deporting this or that person. They current system makes the rest of us less safe -- and that's not even getting into the massive impingement on the human rights of law abiding folks due to the misincented immigration (and other) laws and their enforcement).
Where undocumented immigrants won't be able to file their taxes is if they used a counterfeit SSN to be employed, but even in those cases they pay anyways through standard withholding. Most Americans don't know you can adjust withholding, nevermind undocumented immigrants.
