MA NR LTC is very doable and many times easier to obtain (unrestricted) than a Resident LTC. State issues NR LTCs and pretty much keeps to MGL for the requirements. Each city/town's police chief gets to make up their own "add on requirements" in MA for Resident LTCs, so it is a real crap-shoot.
I understand that RI regularly denies for "insufficient reason" their permits and even on renewals . . . both Resident and NR. Thus, I've never bothered to apply there.
I would NOT recommend living in MA under any circumstances! If you do decide to move there anyway, contact (and join) GOAL for advice on what towns are likely to give you less hassle. 508-393-5333,
