they are strict on you not leaving the country with local currency, so you are likely to struggle to exchange it here, you will need to talk to a broker. You may need to take a holiday and enjoy it all. Oh, but you're not supposed to enter with it either!!
mash is correct, we were advised not to take money out of the country because of the fragile economy and if we were caught we'd be in trouble! Scary stuff. I would speak to a broker for advise 1st.
