As of Aug. 10, 2012, U.S. Customs and Border Protection (CBP) no longer provides admission stamps on Forms I-20/DS-2019 for prospective and returning international students and scholars (traveling with F, M, and J visas) seeking admission to the United States. This change makes CBP processes consistent with U.S. Citizenship and Immigration Service’s (USCIS) recent change to stop stamping Forms I-20/DS-2019.
USCIS implemented this change as part of the launch of its online immigration benefits system, USCIS Electronic Immigration System, as it transforms the agency from a paper-based system to an online environment.

Although placing an admission stamp on Forms I-20/DS-2019 has been a longstanding practice at CBP, it is not required. While the admission stamps on Forms I-20/DS-2019 are not indicators of lawful status or academic program duration, some state and federal benefit granting agencies have required international students and scholars to present stamped versions. State requirements vary.
