Visa Infomation

The President of the United States has signed an Executive Order relating to visa issuance, screening procedures, and refugees which restricts entry into the United States by refugees and some visa holders. Please be assured that ICERM will continue to process all applications and requests for visas as usual. The Executive Order will not in any way affect an applicant’s chance for acceptance into our programs and, if accepted, their spot will be held until they are able to secure a visa that is appropriate for the length of their program.

Please note this visa is appropiate only in the following cases:

  • You will be staying at ICERM for 3 weeks or fewer, AND
  • Your invitation letter indicates you will be receiving reimbursement from ICERM,
  • OR you are receiving funding from another source and your stay is 90 days or fewer

    To see if your country is on the Visa Waiver Program list please go to this website: U.S. Department of State website.

    Under the VWP program, you are required to fill out an Electronic System for Travel Authorization (ESTA) application (for a minimal fee), and will automatically be enrolled in the Department of Homeland Security's US-VISIT program. While this can be done a few days prior to your trip, we advise it be done as soon as possible in case you are denied online approval.

    If you meet all criteria for Visa Waiver and your ESTA is approved, you do not need to visit a US consulate or embassy before your trip. All visitors traveling under the Visa Waiver Program MUST present machine-readable passports at their port of entry into the United States.

    If you have any questions please contact

    If another U.S. institution supported your visa application, please let ICERM staff ( know your status immediately upon acceptance of your invitation. There are certain restrictions and advanced arrangements you must make with your visa sponsor (typically your home institution's Office of International Student and Scholars). When contacting ICERM staff please note your country of citizenship.

    Canadian citizens may request entry into the U.S. as a visitor for business without going to an embassy or consulate office. A Canadian citizen presents at the U.S. border:

    • Letter of invitation from Brown University/ICERM (Please contact ICERM staff at for this letter).
    • Passport

    If you do not fall into the above categories please contact the ICERM staff at for assistance. In your email please note your country of citizenship and dates of intended stay at ICERM.

    Please note that the visa process can take anywhere from 5 to 14 weeks to be completed. As such, we advise participants to start the process as soon as possible.
