Flight hours go with you wherever you go. The new flight instructor will probably want to take a flight or two to just see where you are at, so there might be a little extra flying involved but not more than an hour or two... The place where your experience won't necessarily transfer over is at a part 141 school... You may be able to apply some time towards the course, but given your situation I would go to a part 61 school, at least at college... To start it doesn't matter.
