Can I bring my father to the US if he has multiple felonies?

He is an immediate relative and yes you can petition for him to come to the U.S. There are two stages to the process and the first stage your relationship should be fine is you are over 21 and a U.S. citizen. The second part is his own petition to immigrate. We would need to review his deportation order and all of the documents relating to his criminal convictions to see if these will preclude his immigrating, are too old to be a problem or are waivable. We would be happy to consult with you on these issues but it would be helpful to obtain what you can on the deportation and criminal records - if you don't have these we can assist you or him in obtaining them. We do charge for consultations but whatever is paid for the consultation would then be a credit toward the fees for his case if you decide to move forward with his case.

Even after being outside the U.S. for 10 years he still may be inadmissible due to the multiple felonies. Also, since at least one of the convictions involves drugs he may be permanently barred from immigrating the U.S. Under Section 212(a)(2)(A)(II) and 212(a)(2)(C), individuals who have used drugs in the past, or who have sold drugs in the past are barred from immigrating to the U.S..
