The ISO has been operating remotely, with no in-person office hours, since March 19, 2021 due to the COVID-19 pandemic. The ISO is providing full services online/remote until further notice.
ISO Staff continue to answer our main phone line, respond to inquiries to the ISO-Help@mit.edu email, and ISO Advisors can be contacted by email. Students wishing to schedule an online meeting with their ISO Advisor by Zoom can email their ISO Advisor to set up a meeting time.
Thank you for your assistance and understanding.

The business hours for the International Students Office are from 9am–4pm (EST) on weekdays from Monday-Friday. The office closes every Wednesday morning from 10:00am–11:30am for an organizational meeting.

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.
