An earlier Presidential Proclamation from March suspending the entry of most non-U.S. nationals entering the United States from select countries has been updated to include Brazil. According to the proclamation, travelers arriving directly from the following countries are affected:

• The People’s Republic of China (excluding the Special Administrative Regions of Hong Kong and Macau)
• The Islamic Republic of Iran
• The Schengen Area
• The United Kingdom (excluding overseas territories outside of Europe)
• The Republic of Ireland

Entry into the United States is suspended for travelers, including immigrants, non-immigrants, and most non-U.S. nationals who were physically present within the named countries during the 14-day period preceding their entry or attempted entry into the United States. UC Davis international students and scholars should be aware that individuals who have returned home to these countries or are traveling through these countries will not be permitted to enter the U.S. at this time.
