shaaji, first of all you should check on your I-140 again..as far as i know, from early this year, all my friends and colleagues on non-concurrent cases got it approved within 2 months..its been 4 for you..
big bad wolf,what u say is fine but i think it also makes sense for non-concurrent people to look at just one sheet related to them - adding it to concurrent is of no use especially with drastically different processing times these days for concurrent
