I always see people complaining about immigration problems with family members or spouses and many have replied to write a letter to immigration about their complains. I was wondering what USCIS does with those letters, if there actually investagated or kept in file in the green card holders record. What if the complain was about fraud or adultery? Will the Green card be able to renew there green card or file citizenship if there is a complain about them, and all the suporting paperwork is attached with the complain letter?
