Language
Applicants for naturalization must be able to read, write, speak, and understand words in ordinary usage in the English language. Applicants exempt from this requirement are those who on the date of filing:
have been residing in the United States subsequent to a lawful admission for permanent residence for at least 15 years and are over 55 years of age;
have been residing in the United States subsequent to a lawful admission for permanent residence for at least 20 years and are over 50 years of age; or
have a medically determinable physical or mental impairment, where the impairment affects the applicants ability to learn English.
This is still BS and yes, my tagline is sarcasm......
