Hello All, To kill time and not be depressed i have taken to fooling around with USCIS case# and i am mystified and would want your opinions or take if you have noticed this, i chose a random ZHN17000xxxxx and then did a case search adding 1000 to the number chosen and this is where i got spooked, out of the 1000, ONLY 41 were valid receipt numbers, out of the 41, only 16 had been completed or decided while 25 were either awaiting interview like me or file closed, NOW my question, does anyone have an idea of how receipt numbers are spaced out? I am doing this exercise to maintain my sanity after waiting almost 7 years for interview and to see if theres any noticeable TREND with interview appointments. THANK YOU
