You're right that something doesn't add up, but I doubt it has anything to do with the database....
Are Database Errors Corrected?
The data in the database is an exact replication of the DOL data that was obtained using the Freedom of Information Act. This data is not modified or corrected for errors because a lot can be learned from the errors the data contains. It is not the mission of ZaZona.com to correct errors in our government databases.
So I was wrong, the data is from the Department of Labor instead of INS. HOWEVER, the data IS an exact duplicate of that provided by the DOL. SO, if there's a problem with the data, it is the DOL that either collected the data incorrectly or the data is in fact valid.
