Where do I go in the McCormack Federal Building?
USCIS gives the office location as the John W. McCormack Federal Building, 5 Post Office Square, 14th Floor, Boston, MA 02109. The mailing address adds Suite 1462 at the same street number, and the 14th Floor and Suite 1462 are presented as separate details, so use the floor when you visit and the suite when you mail. USCIS describes the building as on Congress Street between Water and Milk Streets, which helps when a map shows a square and not a street. The page, dated May 18, 2026, and read October 31, 2026, does not describe entry rules or what to bring.
What are the office hours, and how early can I arrive?
USCIS gives clock times here: Monday through Friday, 7:45 a.m. to 4:00 p.m., by appointment only, closed on weekends. USCIS does not state how early to arrive, so treat the time on your notice as fixed and allow extra for getting through the building. From April 20, 2026, the office has stopped in-person information services and does not accept walk-in requests. Check the USCIS closings page before any visit, as weather and other reasons can close the office. Our affirmative asylum guide covers the interview, and Form I-589 filings go by the form's instructions, not to this office.
How do I get to Post Office Square by T or by car?
For public transit, USCIS only points to the MBTA at mbta.com for stops, schedules and fares, and names no station, so plan the route there. By car, take I-93 to the State Street exit, head west on State Street and turn left onto Congress Street. The building is on Congress Street between Water and Milk Streets. USCIS says only that there is limited parking near the office and gives no price or garage name, so we do not name one. If you are coming from elsewhere in New England, allow for that drive on the morning itself. The office is accessible to people with disabilities, and interview accommodations go through the Contact Center at 1-800-375-5283, Monday to Friday, 8 a.m. to 8 p.m. Eastern.
Which New England states go to the Boston Asylum Office?
USCIS lists five: Maine, Massachusetts, New Hampshire, Rhode Island and Vermont. Connecticut is not on this page's list, so do not assume all of New England belongs here, and the page names no second interview site in these states. To update your address or ask about an accommodation, use the USCIS Contact Center or uscis.gov/ar-11. Office contacts are 617-574-3600, fax 617-574-3601 and bostonasylumoffice@uscis.dhs.gov. Your notice sets the place, wherever in these five states you live.
Is this the same as the Boston or Chelmsford immigration court?
No. EOIR lists two courts in Massachusetts that often come up in the same search: the Boston Immigration Court at 15 New Sudbury Street, Room 320 and the Chelmsford court at 150 Apollo Drive, Suite 100. Both are EOIR, and Post Office Square is USCIS. If you have an interview notice, none of those court rooms is your destination. If your envelope holds a Notice of Hearing, follow it, and use our guide to verifying a hearing date, court and judge. A missed hearing has serious consequences, covered in our page on orders issued in your absence.
