What can I do to prevent my boyfriend from being deported?

Any attorney will need a lot more information to make such a decision - when did he enter the U.S., how, any criminal record, permanent resident or U.S. citizen relatives, any prior border stops, are you considering marriage, your status, age of the child, other equities for a non-LPR cancellation of removal case if at least ten years presence in the U.S., etc. If you would like a consultation on the facts of your specific case feel free to contact me as indicated below. I do charge for consultations but whatever you pay for the consultation would then be a credit toward the fees for your case if we are retained for services after the consultation.
