I would like the mailing address of USCIS and/or ICE. I would like to write to them.
As my colleagues stated there is readily available contact information. However the deeper question is why are you writing to them. Many times I have seen clients who try to communicate with officers on their cases only to make matters worse. Get good counsel immediately and do not communicate unless you seek immigration counsel first. If you are already represented please do not make the mistake of communicating without your counsel. Seek help from an excellent immigration attorney in your area.
