The H-1B Visa Fraud Crackdown Act increases financial penalties and prison sentences for companies and individuals that violate the H-1B visa program rules. The bill significantly raises fines for serious H-1B violations from $5,000 to $100,000 for first offenses and from $35,000 to $250,000 for subsequent violations, while extending prison sentences from 2-3 years to 5-10 years respectively. It also increases penalties for document fraud related to visa applications, raising fines from $250-$2,000 to $1,000-$10,000 for first offenses and from $2,000-$5,000 to $20,000-$50,000 for repeat violations. The legislation affects employers who sponsor foreign workers on H-1B visas as well as individuals who commit fraud in the visa application process. The bill contains no specified funding requirements or implementation timelines beyond the penalty increases themselves.
