While the ISO is operating remotely, it will take longer to respond to any documentation received by paper mail. We encourage that paper mail not be sent to the ISO during this time, but rather that you consult with your ISO Advisor first before mailing any documentation to the ISO (it may be preferred that documentation be scanned/emailed to your ISO Advisor).

The International Students Office does not answer questions regarding international student admissions, degree programs, billing, financial aid, and housing. Please refer to those MIT offices to find the quickest answers to your questions.
