In general, if you go from one country to the next, your experience hours are transferable. But you'll have to start all over again on the theory exams.
Make sure the flight school signs your logbook/hours as being correct, or supplies some other type of verification paperwork. Furthermore, you may need to submit a request to the new aviation authority so that they will recognize those hours. The rules on this vary from country to country.
Like MJ said, we'll be able to give you a lot more detailed information if you tell us the names of the countries involved.
