I'm not sure why someone here is so intent on impugning someone else's integrity. And the 'my PRA rep is better than your PRA rep' stuff is just childish. I'm sure your rep is the greatest.
As for me, I do not recall being charged anything for SRRV services. The SRRV application was fairly routine. Although the WISE process of funding the Classic with Pension was a little tricky doing it from overseas (here). And the FBI clearance was all new to me too. Getting local police to do it was kind of funny actually! Prisoners in the jail were handing me alcohol spray to get the ink off my fingers, etc.
As for the other matter, I am extremely happy that Mr Biron personally handled my overstay issue. By approaching BI with my personal information, including my immigration status, I was identifying myself to BI as 'subject to immediate deportation' and I was also disclosing my location to BI. I could have been immediately deported. My life (wife & son) is here now, so (permanent) deportation was a potential fiasco.
That's when having a bright, knowledgeable, helpful immigration expert with a solid legal background and a stellar reputation, who is on very good with various BI staffers and officials comes in handy. To plead my case. Could I have done it successfully without local help? I seriously doubt it.
