It basically starts with the administration in accepting and legalizing the use of BTC in the respective state. In many countries, the administration is still sceptical about the nature and properties of digital currency. It may be mainly because BTC is decentralized and not under the control of the state. Until the administration starts to accept the concept of cryptocurrencies, the local businesses would also steer clear. Nobody wants to upset the big brother 
I think by administration you mean the states which I think will take a longer time or no one can say that when will the state legalize bitcoin as Japan now has legalized for which no one expected. The better way is that we the users of bitcoin ourselves need to work for it to make it acceptable in the local market and to regulate it without any issue to the merchants.
This reply would be good if you reply few months before. Please continuously read the coindesk news about the bitcoin adoption and the country's passing bills in the assembly for bitcoin centralization.
There is no need of effort to provide to make bitcoin to be use in local businesses. bitcoin will be in competition between Paypal and WU. Then automatically it would be happen.
