I would contact the Florida state massage board first and ask if they have ever had someone transfer hours from a school in another state to Florida as an "add-on" of education hours.
Then, I would contact the school you plan to go to in Virginia to ask if they have ever transferred hours before. See what their protocol is and how they normally do this.
Then, I would follow up again with the Florida state massage board and let them know what your school in Virginia proposes to do and make sure that will fly with them.
Of course, I usually double and triple check things like this because depending on the person you get on the phone you may get a different answer than if you call back in 15 minutes and get another person.
A prime example of this happened to me just the other day when I contacted Microsoft to purchase "Office 2010"... I called and spoke to someone about the new version I purchased that doesn't work with Windows XP. He told me I needed 2010 and that I could purchase it through them. So, I took the wrong version back to the store (they aren't carrying 2010) in our local stores anymore. Then I came back to work and got on the phone with Microsoft again and spoek to another gentleman who told me they *don't* have a 2010 I can purchase and that I would need to get it from Amazon or whereever. After 15 mins. on the phone with him and figuring out he was clueless as to what he was jabbering about, I hung up and called Microsoft again, and got a lady who was able to create the transaction for a 2010 version right that minute. I purchased it via credit card, it was sent to me and the rest is history. You just can't trust everyone on the phone, even though they tell you they know what's going on.
I'd be sure to get as much in writing too.
Please come back and tell us the proceedure and how it all shakes out for you.
