R You Sure that they are legally obliged
Whether they are legally obliged or not, but I did not get any reply from them even after faxing 26 times and mailing 19 times for my Finger Printing Notice in Nov/Dec 2001. And now I have Faxed 7 times, (2 times to the officer who is handling my case and 5 times to the Director INS, till yesterday from April 3, 2002 I am going to fax one more today) enquiring the status on my case.
I AM USING 214-767-7654 (If this is the right number) I am getting it thru the fax between 9.00 AM - 10.00 AM.
