A lot of comments in this thread discuss the status of the buyer in relation to getting a delay/undetermined response from DOJ.
But delay/undetermined responses are quite often caused by factors unrelated to the buyer, and beyond the buyer's control.
All through my LE career, I've had to sort through automated criminal history records ("Rap Sheets"). That's not a simple task. Rap sheet records are not universally maintained, and the quality control over records varies considerably between agencies. An agency is supposed to create a record when a person is arrested, update the record when a charging decision is made, and then update again when the case is closed. Those updates don't always get made. I've seen a lot of court cases pending since the 60's.
Add to that the fact that many folks have similar names and descriptions, and that some folks use another's identity when booked. California requires a fingerprint ID to create a booking record, but many states believe whatever an arrestee tells them.
The net result is that if I run a criminal history check on Pedro Martinez (DOB: 01-30-1990) with an address of 123 Main St. in Ventura, I may get a return showing a felony to Pedro Martinez-Gutierrez with a DOB of 02-30-1990.
That begins the process of "deconflicting" the rap sheet return. That's usually done by examining other records concerning the subject. I'll go to other databases to see if Mr. Martinez has a middle name of Gutierrez recorded. I'll also examine the source of the record showing the February 30th birthdate. Many computer systems require a "Month-Day-Year" input, and the nice booking officer may only know the approximate age of the arrestee. A lot of agencies "dummy up" a DOB in such cases by using the February 30th date. At some point, after looking at all of the available records, I gotta make a decision if the rap sheet actually belongs to the subject I'm looking at, and that decision often involves conflicting information. It's a subjective decision and different reviewers may make different decisions from the same information.
A lot of folks do not like putting their SSN on the Form 4473 (it's optional) based on privacy reasons. The SSN does not get used in a comparison of the primary records used to compile criminal histories, but it does often appear in the collateral records that may be accessed to deconflict a criminal history record.
