Will my son be deported after being in and out of jail for the past three years?

You should consult an immigration attorney: whether or not your son can avoid deportation depends on the convictions on his record, and on your family circumstances. You should not delay getting professional help with the case because the Immigration and Customs Enforcement can move your son to a detention facility in another state (most often, to Texas, New Mexico, or Louisiana), and defending him will become more difficult.

Yes. You need to sit down with an attorney and provide his entire criminal record and immigration record.

You will want to consult with an immigration attorney with a copy of his criminal charges. If you became a US citizen when he was young enough there may be a small chance he became a US citizen at the same time you did. It may also be that his home country will not accept him to be returned, or the Convention Against Torture may prevent his return.

Have you and his father become naturalized US citizens yet? If so, when were you naturalized.

There may be a chance to fight the deportation and apply for Cancellation of Removal. You need to hire an immigration attorney to review all teh facts and give compentent advice on this process and likelihood of success.

My recommendation would be to speak with an Immigration attorney and to do so immediately, if not sooner. Kind of difficult to tell you whether you son will be eligible for any type of relief from removal and deportation based on the information that you have provided below. There is a huge difference in the possibilities available if your son entered the US as a refugee and never became a resident as opposed to entering the US as a refugee and having filed and been approved for his residency. So the best way to deal with this is to schedule an appointment with someone who handles removal cases. Not someone who does immigration work, someone who knows his or her way around an Immigration Court and can find the pathways to resolution of the case that may be available. This does not sound like an easy case and perhaps there is nothing that can be done. Nonetheless, speaking to someone who knows what they are doing is the best way to become informed and to figure out whether there is some resolution out there. Good luck.

It depends on what crimes he has committed. You should speak with an experienced immigration attorney to figure out what your options are.
