We now have Andrew's case ID

As outlined in previous posts, we are trying to track down Andrew and Joseph's naturalization papers.  The first step to doing so is getting their file numbers.  We made a request for the file number in  January and received the answer in May (so about four months).  And here's a picture of the letter with his file number (C-4714359):

We have used this to make a request for the actual naturalization record.  Hopefully that will come through soon too.
