International Center

Letter Requests

Letters will only be issued upon request.  Delays can be expected during peak business times.

Letter Requests 

The International Center will only issue the following letters on letterhead through submitting a "Letter Request" within the ISSS Portal:

  • Immigration Status Verification
  • Proof of Residency
  • Social Security Letters
    • The International Center will sign these letters from the Illinois Institute of Technology on-campus hiring department once the student uploads their letter within the "Letter Request" submission in the ISSS Portal. If the hiring department is not able to issue the Social Security Letter, please have them contact the student employment office.
  • Signature Required-Other
    • There may be miscellaneous, non-Illinois Tech forms that require a signature from the International Center which the student will provide as an upload within the "Letter Request" submission in the ISSS Portal for validation.

*The International Center does not provide Enrollment Verification Letters. For enrollment letters, you must request an enrollment certification through the MyIIT portal.

Invitation Letter

Invitation letters issued by IIT are not required by the US Embassy or Consulate to issue a B-2 tourist visa, and so the International Center will not provide invitation letters to students. If you have family or friends that would like to visit you in the US, you may provide them with your own invitation letter. The letter should include your name, identify the person you are inviting, their relationship to you, and state the duration and purpose of the trip.

Please contact the US Embassy or Consulate where your family or friends will be applying for their B-2 tourist visa for the specific list of documentation that is required to apply.
