@Em**
hope to meet you at FCCT.
Coming in on a different visa is a good idea. And plan b could be to open your own business, as a few other freelancers have done.
I know that there are about 600 or so applications for press credentials submitted each year but only a small percentage are granted. The government wants as much control as possible and freelancers are hard to control. They don't have a parent company that can be held accountable or penalized.
Still, there are several freelancers that are regular contributors to different news agencies that are able to get the visa and credentials. You just have to keep at it.
