If you are seeking a waiver for the citizenship examination due to a mental disability, a psychologist can conduct an unbiased and objective assessment to establish the nature and extent of the disability. If there is sufficient impairment, the immigration psychologist can complete a medical certification stating that you have a mental disability that prevents you from taking the examination. The medical certification should include information about the nature and extent of your disability, and how it affects your ability to take the examination.
In order to be considered for the exemption from the citizenship test, you will need to provide this medical certification (N-648) along with any additional documentation or information that may be requested by the immigration authorities.
It is important to note that each case is evaluated on a case-by-case basis and the decision to grant a waiver is at the discretion of the immigration authorities. The immigration psychologist is not a legal expert and cannot give legal advice. It is the immigration attorney who handles all legal matters.
