I’m in Massachusetts and we have no CEU’s and it is only $66 per year for licensing. Check with your licensing board to see if it is easy to get re-instated after having continued licensing in other states. I’d leave out the fact that you’ll be abroad. They will likely think you’ll be practicing in that other state, although it should not matter in my opinion.
Massachusetts is a Title Act state rather than a Practice Act state (hard to believe with Harvard here and Olmsted’s history here). You might want to stick to a Practice Act state to avoid the possibility of any issue.
