On January 24, 2023 Texas and 19 other states filed suit in the United States District Court for the Southern District of Texas, against the Department of Homeland Security and related parties, alleging the agency "has effectively created a new visa program - without the formalities of legislation from Congress - by announcing that it will permit up to 360,000 aliens annually from Cuba, Haiti, Nicaragua, and Venezuela to be 'paroled' into the United States for two years or longer and with eligibility for employment authorization."
