Me and my wife's LUD changed for 485 as well.
No big deal. Nothing to get excited about.

08/17/2006: USCIS Data Digitalization Facility in Williamsburg, Kentucky and Electronization of Immigration Benefits Filing and Processing Agenda
* USCIS announced that the USCIS had opened this facility to manage almost one million alien files digitalized and stored for retrieval by field offices for future electronic filing and processing of immigration benefits applications in the near future. As we reported earlier, the USCIS has been pushing reengineering of the immigration benefits filing and processing into electronization and the petitioners, aliens, and their lawyers will be required to electronically register and once the database is digitalized, the digitalized data will be shared by the field offices when they process the immigration benefits applications. This will enhance the speed of the processing as well as the national security plus fraud prevention and detection. Reportedly there are 70 million alien files which need to be digitalize in the future. We anticipate that the immigrant community may see a different filing system and procedures in coming year once the reengineered process and system are in place for operation.
* The benefits of digitalization are illustrated by the digitalization of fingerprinting. In old days, the fingerprint was taken manually using ink. Now it is taken and digitalized. Once the I-485 is approved, the digitalized data is transmitted to the plastic green card production facility and the plastic card is almost instantaneously produced and shipped out the new immigrants. In old days, people had to wait for six months or one year to receive the plastic card, but now thanks to digitalization, people receive the plastic green card in less than 10 days in the mail. Certainly the digitalization will compromise the people's right to privacy but it appears that it is the price the people will have to pay to benefit from the electronic processing of immigration benefits processing.
