For those who filed I140/I485 case concurrently, use your I485 case number minus your I140 case number, how much do you get? please list here, let's do a statistics, just give the digits apart here, not your actual cases numbers.
You may randomly check the case numbers between your I140 and I485 numbers to see how other cases are doing.
does anyone get a negative number, which means your I485 has a case number before your I140 case number?
