Thank you engray!There is usually a letter with the returned package that instructs you on what to do. Some people needed to just resubmit the same application after attaching the correct documents, and some needed to prepare new application and attach new physical presence calculations. I would read the letter thoroughly.
You're correct. There was a letter attached to each application. however, it doesn't say anything clearly. It says "If you choose to resubmit a complete application for a grant of citizenship, make sure you include the completed application form submitted on a version of the application form dated October 2017 or later. I don;t understand what do they mean by "complete application". The version that I submitted was 10-2020, so I don't see any issue in that aspect. So now I am confused, If I have to fill a new application from scratch or just attach the document they requested to the returned package and resubmit.
