I really have no idea what stage of the process I am now. Anybody who can tell me approximately how many percent of the processing was already accomplished? Thankiezzz!

you are at the very beginning of the process. My understanding is I140 shows that you are qualified for the job and that the hospital has done what is necessary to find someone locally for the job and that they are able to pay you the same wage as a US RN.
Once you have approval that is when you are hit with retrogression and now join the queue for patience and perciverience whilst waiting for visas to be allocated. Your file once approved is moved to the NVC centre and they will process further once visas are available.
Suggest a really good read through the many thread especially on retrogression and things should be a little bit clearer for you
Hope this helps
