H-1B workers entering the US might face a serious question from Customs and Border Protection (CBP) officers: "Have you ever paid any portion of your salary to your employer?" Murthy Law Firm warns that if the answer is yes, the worker could be removed from the US and face a five-year re-entry ban. Many H-1B employees misunderstand this question and risk their stay in America by giving wrong answers. The law firm advises workers to carefully review their employment contracts and salary structures. This helps ensure they follow H-1B rules and are ready for questions by CBP or other immigration officials. Typically, a client hires a staffing firm that provides an employee for their service needs. The firm bills the client and pays its employee a salary. It is normal for the firm to charge the client more than the employee's pay. This extra covers the firm's expenses like administration and taxes. Some firms use a revenue-sharing model, telling employees they earn 75% of the money the client pays. But this does NOT mean the employee pays the employer any salary portion back. Murthy Law Firm warns H-1B workers to be careful if asked to pay or reimburse H-1B filing fees, face unusual payroll deductions, or return parts of their salary in cash. These are illegal practices and can cause serious immigration trouble. H-1B workers must know their rights and keep away from salary schemes that break the law, or they risk being barred from the US.
