Clearance limit of VFR practice IFR approach?
I'm assuming you're asking about the US, in which case the answer is no. The AIM 4-3-1(e) says:


  VFR aircraft practicing instrument approaches are not automatically
  authorized to execute the missed approach procedure. This
  authorization must be specifically requested by the pilot and approved
  by the controller. Separation will not be provided unless the missed
  approach has been approved by ATC.
