sorry for misleading informatino. They did not ask for W2 for the past 5 years. They just asked all W2 from my last role (from 2008-2010), then my latest paystub for my current role.
I am not worried about W2's as they are just used to verify my working status in my last role. As I am always in the same company for the latest few jobs, I asked them not to contact my current company (also the company for my last few jobs). Then they asked me to send W2's to confirm the employment status in the past.
Thank you!!
