I have a similar issue but Mass plates. Sticker expires in January each year. MASS RMV has an option on their webpage that allows me to acknowledge that the sticker is expired and that I will get it inspected upon my return to Massachusetts.
Having said that, I wouldn’t worry about it. Just get it inspected upon your return. Even if you get stopped for it, I would think most officers would find your story believable. Don’t remove the sticker. It’s better to have an expired sticker than no sticker at all.
