I got a call from Collabera which is a IT recruiting company. Everyone is from from India but have offices in NY and NJ. The problem I have with them is that they wanted my SS# and emails and documents that I have work for these companies. When I ask why I have Reference that you can call they said that they need records.
So question is, is it legal to ask for my SS# and private emails and even W2/4/9?
