USCIS frequently is juggling around case types between various service centers to try and assure that all case types are adjudicated as quickly as possible. Fairly recently they started transferring EB-1A Extraordinary Ability cases to Nebraska from the Texas Service Center. Even more recent certain H-1Bs were sent from Vermont to California and Nebraska.
Recently, USCIS started a new webpage on their site devoted to such transfers. This webpage lists all recent transfers and gives some information on what the transfer means to your case and how you can check the status of your case online. In reality, once USCIS transfers files to a new service center, that service center usually slows down slightly for a little while before they are able to catch up on all the new cases they have received. In some cases, the new service center slows down so much, that it actually takes longer than it appeared to be taking at the old service center. This is an unfortunate consequence, however there is no way to request that your file be sent back to the old center. Following the timelines where your case is and filing requests for information once your date has been reached is the best bet to ensure smooth processing in your case.
