This is what IIO says..and what NVC says - abt connxn
the connection is made ONLY WHEN YOUR FILE (I-485) IS ASSIGNED TO AN OFFICER
Until FP,the entire process is with no human intervention- when I say this,is that the only things checked are for valid docs,etc..i.e. do u have ur I-94,etc.
noone is perusing each doc.FP itself is generated automatically based on ur local INS availability and I-485 RD.
Hence,when the SC is adjudicating cases with ur RD,that\'s when an IIO actually starts perusing each doc,and goes thru RFE/approval,etc
And that\'s when the connection to ur I-140 is made.
*BUT - the I-140 may or may not be asked for by IIO - usually it is.
Hope this helps..
I too had my I-140 approved for CP,unintentionally...
Cheers
