The application for registration is pretty clear. I am surprised it took them this long.

> NOTE: Dual Registration is when motor vehicles or trailers registered in another state need to be registered in MA under the dual registration concept (MGL Chapter 90, Section 3) and display plates from both jurisdictions (as required in MGL Chapter 90, Section 6). This applies to vehicles that meet all of the following conditions:

> • Owned by nonresidents

> • Registered in another state

> • In the possession of, or under the control of, MA residents for more than 30 days (not necessarily consecutive) within a calendar year period
