"Bank of America and Wells Fargo are doing the same thing!!!!"
Not true.
Not with mortgages, possibly on the deposit side.
All borrowers must have residency status documented.
I know because I had potential customers fall on the undocumented side and they cannot get financing.
I just switched jobs from one of these companies to the other this month.
I meant that they are soliciting for depositors who are illegal. I know they can't legallly write mortgage paper yet, but they are lobbying fiercely for it.
