Two operators of several Key West labor staffing companies — including PSEB Services Inc., E.S.F. Services Inc. and Expert Services F.S. Inc. — were each sentenced to more than three years in prison on Monday, April 22, for tax and immigration-related crimes.

At various times between January 2014 and October 2019, Zdenek Strnad, Vasil Khatiashvili and others helped run a series of labor staffing companies that facilitated the employment in hotels, bars and restaurants in Key West and elsewhere of non-resident aliens who were not authorized to work in the United States, according to court documents and statements made in court.
