请问PJIANG老师和小白兔：关于NC PROVACY ACT REQUEST一定要公证吗？

尊敬的老师，您好！现有一事相求，近日收到一封FBI有关我们就移民问题查询NAME CHECK的回信，他们要求我们填写一份,是这样要求的“therefore, in order to provide you with information contained in our system of records, it is required that a signed and notarized Privacy Act Request form be completed."

请问：1，一定要"notarized"公证吗？2，如何公证，去什么机构公证呢？
敬盼回复，谢谢！
