Sinp filed on jan 4 17

SINP filed on jan 4 17. No news yet. status shows in progress. I tried contacting them, they said - it's progress and no documents needed from you. Is it the same case for other applicants too?
Hello All, I applied to SINP on Jan 4th. I got a request for additional information on March 28 and submitted early April. Status did not change to in process until early May.....Status subsequently changed to In Process but I would like to know if anyone is in a similar position and for the more experienced applicants any best estimate on the time to nomination?
Similar incident happened with me as well. They asked for additional documents in march and now it's in in-progress state. I think, we have to wait until it gets changed.
