It depends on your training program, employer, and state.
Certain programs (i.e. LSU) you would probably have enough hands on experience to do lumbar ESIs, MBB/RFA, and SI joints. For an individual right out of training I would not sign off at our facility unless you performed at least 50 supervised independent performed ESIs and MBBs/RFAs with evidence that you did them correctly and/or could identify vascular/dangerous flow and do the appropriate correction. Plus your residency director would need to sign off that you are competent through this request for procedure form and most seem hesitant to do that for a resident without fellowship training. Personally I would not sign off on someone to do cervical injections right out of training unless they are fellowship trained.
If you/your practice had an in office fluoro suite then you could do whatever you wanted to do if you got approved for payment by your insurance payors or just did it cash based with appropriate disclosure.
Doing a pain or spine fellowship (or PM&R sports that offers spine training) will be a huge benefit for your future if you want to do spine procedures.
