The main purpose of this legislation, known as the Timely Departure Act, is to establish a financial requirement for nonimmigrants seeking to enter the United States and to impose penalties on those who do not leave the country on time. The goal is to ensure that individuals who come to the U.S. temporarily adhere to their authorized stay and depart as required. One of the key provisions of this law is that nonimmigrants must pay a bond or cash payment ranging from $5,000 to $50,000 when they apply for admission. This payment is intended to guarantee that they will leave the U.S.
