We sent you a notice on February 27, 2018 to appear and write the citizenship test on March 22, 2018 at 8:30 AM.
The details of location of the test center, what is needed to bring etc will be in the postal mail?
Basically, they are asking to bring the original documents that are listed in the citizenship application checklist, when you applied, to the Citizenship Test. That's all.
