Fyi, Warwick, RI does walk ins after 4. I had an appointment yesterday at the end I asked the officer about the scheduling for my wife and two daughters. I had made appointments for them in March, except I could not get one for my youngest daughter. So I asked if the daughters could just go with my wife's appointment. That is when he said they do walk ins after 4. He said it is a good idea to call after 12 to check if they are doing them that day. He mentioned he was going to be there today so I brought the three of them down and got it all done, only one person was ahead of us. We live in southern MA so Warwick is much easier to go to rather than Logan, the Warwick office is in an office building a mile from 95, plenty of parking, easy in and out.
