Vacation pay still due if transfured to another state?

I worked with a company for almost 5 yrs. i was transfured to another location (CT) to "help them out" for the last 4 months of my employment, and chose to leave the company. I gave an ample 30 day notice. I was still working in CT when I left, but work 4.5 yrs in mass where my vacation time was actually earned, am I still owed that time? My employer give 2 weeks a yr use it or lose it.
