Anton Vialtsin, Esq., E.I., handled hundreds of federal criminal cases, which required in-depth knowledge of the Federal Sentencing Guidelines and the Criminal Codes and Rules. Over two dozen cases involved importation and distribution of controlled substances all punishable by ten-year minimum mandatory sentence (21 USC §§ 952, 960, 963). Working in the Southern District of California (a border district and one of the busiest), he defended individuals charged with transportation and harboring of illegal aliens (8 USC §1324), misuse of a passport, and illegal entry into the United States (8 USC §1326). Further, he worked on several transportation-of-aliens cases resulting in death, triggering the possibility of the death penalty. He worked on complex wire and mail fraud violations, aggravated identity thefts, and thefts of public property.

While handling federal cases, Anton Vialtsin also runs a successful California state practice.
