V wants to get A deported (grounds for deportation)
We can't provide specific information on how to have someone deported, but we can provide general information on reasons that a person might be removed from the U.S. There may be a number of reasons that a person could be deported. For example, a person who has been convicted of certain crimes could be deported. While we do not have detailed information on this topic on our website, I did some outside research and found this list, which has examples of reasons a person might be deported: http://www.legalmatch.com/law-library/article/deportability-grounds.html However, this is an outside website that we have no relationship with, so I cannot guarantee its accuracy, but am simply providing it for your information.
One option might be to contact an attorney who specializes in immigration and ask about whether or not you could withdraw your sponsorship and/or if there is anything else you might be able to do. We have a list of agencies on our website that specialize in immigration, and who might be able to provide a referral to an immigration attorney: http://www.womenslaw.org/gethelp_national_type.php?type_id=1047
