To the OP....I just obtained my RI CCW license in RI through my hometown in Johnston. During the process, the detective I dealt with was very helpful in assisting me, and offered some insight.
He told me as long as someone holds a valid permit in any other state, the town of Johnston will issue you a non-res permit with identical restrictions as your home state permit. Johnston isn't too far from Attleboro. If you apply through them, you will get it. He also advised to never apply through AG because denial is more likely, and once you are denied once it is harder to then apply through a town and get approved. So unless open carry is very important to you, just apply through a town. I also got mine with no restrictions, hope this helps!!
