The following message was sent to Harvard H-1B visa holders earlier today:

Dear Harvard H-1B visa holders, 

On September 20, 2025, the Department of Homeland Security (DHS) shared additional guidance on the presidential proclamation (“Restriction on Entry of Certain Nonimmigrant Workers”). 

The latest guidance from DHS states: 

"This proclamation only applies prospectively to petitions that have not yet been filed. The proclamation does not apply to aliens who: are the beneficiaries of petitions that were filed prior to the effective date of the proclamation, are the beneficiaries of currently approved petitions, or are in possession of validly issued H-1B non-immigrant visas. All officers of United States Citizenship and Immigration Services shall ensure that their decisions are consistent with this guidance. The proclamation does not impact the ability of any current visa holder to travel to or from the United States." 

Again, we continue to work to understand the full impact of this proclamation. Please reach out to your HIO advisor if you have questions about your individual circumstances or review the HIO website for the latest guidance. 

Sincerely,
The Harvard International Office
