Can my father stay in us after serving his sentence?

Hello,   To determine if your father can avoid deportation from the U.S., more information is needed about   the length of his sentence, the type of drug related crime he committed, his criminal and immigration history, etc. Since drug convictions can often lead to a person being put into removal proceedings, it is important that you take the details of your father's criminal case and his U.S. legal residency information and consult with a local immigration attorney in your city to see if he is a good candidate for a criminal waiver. Good luck.   Disclaimer:  The answers to frequently asked questions are based on limited information available to us.    The answer provided is of a general nature and does not establish an attorney - client relationship.  It is not, nor is it intended to be, legal advice.
