She immigrated from Serbia, so maybe that is a cultural difference, but my wife was pretty floored. 

Since I'm a new immigrant with no credit score, a DSCR with 30-35% down payment is my only option, so the 50K need to include that down payment alongside all other costs (closing, rehab, etc). 

You’ll probably want to consult with an immigration attorney to be sure.

Family immigrated to the US 1 month back. 3 children have found jobs at a nearly plant and the father will try to find a job.

DEI policies along with environmental, immigration policies is not sustainable for a non 3rd world country (my guess that is the point). 

As you probably know, California includes all foreign immigration - both legal and illegal to boost the numbers.

You should talk to a lawyer.
