When the I-20 is signed and dated, the student is agreeing to abide by the USCIS (U.S. Citizenship and Immigration Services) Immigration laws governing F-1 status and is responsible for knowing the regulations pertaining to the specific non-immigrant classification. Failure to follow the required federal regulations and procedures in the appropriate manner will result in the loss of legal status in the United States.
Remember, it is the student's responsibility to maintain his/her legal status!
