Acting : Agency for NON-USA'ers by Tammy Vega

Hey there, Ok, so its hard enough to get an agent when you in a different city. Try a different continent. Are there specific agency's that deal with overseas actors? Or a site that posts the casting briefs and you can Skype/email them your audition? Working on a visa currently, but until it comes through, one can only hope to maybe get work. Please help if you can Tam (South Africa)
