For me it really depends. I work a lot in Asia but I usually keep my european rates, which are lower than US rates. However, when working in Singapore or Hong Kong I up my prices to the local rates, which is higher. It really depends what you feel xomfortable doing, but my experience tells me that if someone really wantz to meet you they will pay the fee gladly without making a fuss about it not being "local rates". If you want local rates meet a local boy.
