I suppose it's just like this. I was submitting documents for non-b with an expired 30-days entry stamp. After checking everything the officer gave me some papers to copy (application form and contract I think), then sent to extension section without explaining anything. There they just took papers and gave me back passport in few minutes with an extension stamp until Sep 26. After that I came back to the visa section and finished everything. They took the documents and told me to come back in 15 days
