In general, you can apply for a U visa is you are the victim of certain crimes in the U.S.  You must show that you (a) have suffered substantial physical or mental abuse as a result of having been a victim of "qualifying criminal activity;" (b) possess credible and reliable information establishing that you have knowledge of the details concerning the qualifying criminal activity upon which your petition is based; and (c) have been helpful, are being helpful, or are likely to be helpful to a certifying agency in the investigation or prosecution of the qualifying criminal activity.  INA §101(a)(15)(U), 8 C.F.R. §214.14(b). Qualifying criminal activity includes one or more of the following or any similar activities in violation of federal, state, or local criminal laws: abduction; blackmail; domestic violence; extortion; false imprisonment; felonious assault; female genital mutilation; hostage (being held as a); incest; involuntary servitude; kidnapping; manslaughter; murder; obstruction of justice; peonage; perjury; prostitution; rape; sexual assault; sexual contact (abusive); sexual exploitation; slave trade; torture; trafficking; unlawful criminal restraint; witness tampering; or attempt, conspiracy, or solicitation to commit any of these crimes. INA §101(a)(15)(U)(iii); 8 C.F.R. §214.14(a)(9). Depending on the statute which applies to the muggings, you may qualify under felonious assault  I recommend that you contact an experience immigration attorney to review your case.
