 Latin American countries are multi-ethnic, home to people of different ethnic and national backgrounds.

 Latin America has the largest diasporas of Spaniards, Portuguese, Black Africans, Italians, Lebanese and Japanese in the world.

 NextGen proposes to transform America’s air traffic control system from a radar-based system with radio communication to a satellite-based one.
 GPS technology will be used to shorten routes, save time and fuel, reduce traffic delays, increase capacity, and permit controllers to monitor and manage aircraft with greater safety margins.
 Radio communications will be increasingly replaced by data exchange and automation will reduce the amount of information the air crew must process at one time.
The Equal Nationality Act of 1934 was an American law which allowed foreign-born children of American mothers and alien fathers who had entered America before age 18 and lived in America for five years to apply for American citizenship for the first time.

 This law equalized expatriation, immigration, naturalization, and repatriation between women and men.
