This announcement says that as of 30 June 2020, landlords do not have to do a new TM-30 for someone who goes to stay temporarily in a different place and then returns to the same residence where a TM-30 was already done, as long as the person was using either a multiple entry visa or a reentry permit. (In other words, coming back on a new visa or new exempt entry would require a new TM-30.)
