I'm just bumping this up again to see if anyone has any additional advice. I went to register at the AFIP as a monotributista (so that I can bill my "employer" for my services) and was told that although the precaria enables foreigners to be employed (en relacion de dependencia), you cannot register as a monotributista until you receive the DNI (another 3 to six months time, I'm guessing). Is this right? Has anyone actually attempted this before? I'd really appreciate any advice...don't fancy another few months of illegality and I can't see my boss producing an employment contract anytime soon!! (sigh)
