I made the call today. The lady I spoke to was very friendly about it, although she didn't have any more information on hand than the same old status about being transferred to TSC. She initiated the service request and gave me a confirmation number, saying I should expect a response within 60-90 days but hopefully sooner. Now let's wait and see what happens.
Just wondering, whether it's wise to initiate service request at this point when they are about start adjudicating cases in two weeks. What if they move the application to some queue where they only answer inquiries? I too called NSC this morning but fell short of initiating the service request. Now I'm not too sure whether I should call them again to do so.
