Effective December 4, 2017, the Supreme Court ruled that Presidential Proclamation 9645 (also known as the Travel Ban) can go into effect while legal challenges proceed. This Proclamation partially or fully restricts entry into the United States for nationals of Chad, Iran, Libya, North Korea, Syria, Venezuela, Yemen, and Somalia.

The Proclamation contains specific provisions for each impacted country:

  • Chad, Libya, and Yemen: Entry is allowable for non-immigrant visitors on visas such as F-1, J-1 and H-1B. Entry is suspended for B-1 business visitors, B-2 tourist visitors, and immigrants.
  • Iran: Entry is allowable for visitors on F, M, and J visas. However, these visitors will be subject to enhanced security screening. Entry is suspended for all other immigrant and non-immigrant visitors.
  • North Korea, Somalia, and Syria: Entry is suspended for all immigrant and non-immigrant visitors.
  • Venezuela: All nationals will face increased screening and scrutiny. Entry is specifically suspended for B-1 business visitors and B-2 tourist visitors (and their immediate family members) who hold official positions in government agencies involved in screening and vetting procedures.

While the Proclamation does not specifically call out Iraq in its country specific provisions, the Proclamation does state that there will be increased scrutiny for visa applicants who are Iraqi citizens.


Individuals with citizenship from Chad, Libya, Yemen, Iran, Venezuela and Iraq who are entering the U.S. on allowable statuses should anticipate delays in visa issuance. ISSO will continue to process requests from nationals from the aforementioned countries.

If Departments would like to sponsor individuals with citizenship from North Korea, Somalia and Syria, please contact the ISSO at [email protected] for advice.

Departments should contact their HR representative and ISSO adviser for advice prior to inviting citizens from all of the aforementioned countries.

Please note that UCSF sponsored international students and scholars from impacted countries have been notified of the provisions within Proclamation 9645.

ISSO recognizes that this Proclamation brings uncertainty, and we encourage you to reach out to ISSO at [email protected] with questions or concerns. ISSO is working closely with the UC Office of the President, and our sister UC campuses, as well as our professional organizations (NAFSA, AILA) to monitor the continuing issues impacting our international community. ISSO will remain in close contact with affected communities, as additional information becomes available.
