CSR are contractors and as such don't have access to government systems. Only IOs (Federal employees) have access to USCIS case system. CSR are useful to answer basic questions, but don't have access to answer details on case status. It would cost tax payers more money to hire more IOs just to answer calls about basic immigration questions.Or they might just start training the CSR's better and give them more information which the IO's and the CSR's dont seem to. The CSR is a pointless waste of tax payers and applicants money if you ask me.
