My company hired a law company to apply green card for me and my family. They did a good job, we all have green cards now.
However, they asked for copies of all our green cards, and I don't feel comfortable at all, given the fact that they already have all of our informations, e.g. passports, SSNs, etc etc
I plan to reject this request. However, I wonder if there is any valid/legal reason that they want to keep a copy of our green cards.
