I am writing about an immigration issue for my husband. He has sent in his N400 application for citizenship, and it was received on April 24, 2015. He has done the biometrics appointment. When I called about the status, the customer service representative said they are now working on May 31, 2015 applications, and they haven't sent anything out for my husband. We have done two service requests, and we are currently waiting on a response to the second request (made January 19, 2016) -- it can take up to 30 days to receive a response. The first service request stated that "due to workload factors not related to your case, USCIS anticipates a delay in completing your case. USCIS is committed to adjudicating immigration benefits in the order received and in a timely and efficient manner. We regret any inconvenience that results from delays in processing." Is this normal? Is there anything else we can do? Do you have any idea why USCIS might have skipped over the application?
