Hi, we are planning to do the family/spousal sponsorship in a few months or so. My youngest daughter will be 17 in August. The problem is that we do not have contact with my ex. He was abusive and had supervised visits prior to the last two years of no contact. Even if we could get a hold of him, he has not had a legal ID for over 2 decades, so we would not be able to get a notarized signature or valid ID to send anyways. In the directions, it says that if you cannot supply the signature and ID to send a letter stating why. Is it at all possible for them to accept her with a letter explaining this situation given that she will be almost 18 by the time they finish the year long process?
