Tata Consultancy Services (TCS) is under scrutiny for allegedly misusing L-1A manager visas in the U.S. Ex-employees claim the company misrepresented job roles to bypass H-1B visa restrictions. While lawsuits have been filed against TCS, the company denies wrongdoing, stating compliance with U.S. immigration laws. The U.S. Department of Justice declined to intervene in the lawsuits.
