Final answer:
An authorized official must verify two criteria to issue a blue card: age, residency, moral character, language proficiency, knowledge of U.S. government and history, and willingness to take the Oath of Allegiance.
Step-by-step explanation:
To issue a blue card, an authorized official must verify that two criteria are met:
- Be at least 18 years of age, possess a green card, have resided in the United States as a lawful permanent resident for at least five years, have been physically present in the United States for at least 30 months, be a person of good moral character, and be able to speak, read, write, and understand the English language.
- Have knowledge of U.S. government and history, and be willing and able to take the Oath of Allegiance.
These criteria ensure that the individual is eligible to become a U.S. citizen and demonstrate their commitment to the country.
