As of 3/18/2020 the Boston Immigration Court will only hear detained master calendar and individual hearings. If you have a hearing (and you are not detained) it is crucial that you stay on top of your case. You should call the EOIR hotline at 1-800-898-7180 on a regular basis (every few days) until you learn of the new hearing date. You will need your A# with you when you call.
If you fail to attend the next hearing, you could be ordered removed/deported in abstenia.
Also, if you have recently moved, you must do two things. First, make sure to report your address change to EOIR and ICE. Second, try to get someone at your old address to notify you if you receive any mail at the old address.
