Prior to the online submission of the I-134 form, there was a larger margin for pilot error. But this is considerably less now that it is online as each part of the form is validated. I submitted the form correctly the first time. It's been almost 6 months and nothing other than the initial receipt I received for filing to know that it was in the system. In that time, we have heard of numerous people filing through immigration lawyers who filed after we did already receiving their next steps within 1-2 months. It's not possible that it's a coincidence. So either the government is unfairling giving precedence to forms that were filed by a practitioner, or there is something else shady going on. If you have had a similar experience, please reply to this thread.
