Соединённые Штаты Америки. The transliteration will be 'Soedinyonnye Shtaty Ameriki'.
They are asking if you come from the United "States" of America.
The United States of America.
united states {of America} = états-unis {d'Amérique}
We say "the US" or "the USA", because US stands for United States, and USA stands for United States of America. We would (and do) say "the United States" and "the United States of America", so we say "the US" and "the USA". For some reasons, Americans used to say "the Ukraine", and I cannot explain that. When Ukraine became a separate country, we had to learn to refer to it as simply Ukraine and not the Ukraine.
The United States of America
I would say Jefferson Davis, because he was the president of the Confederate States of America, and Lincoln was president of the United States of America.
Because it's grammaticaly correct. For example, I would say, "I am going to India. After that, I am going to the USA." USA is short for United States of America. So, I would say I am going to the United states of America.
America is a common nickname/alternate name for the United States of America, used mainly by American citizens. It is just another short way to say the country's name just as US, USA, or the United States is. Usually when one hears of America, they still are referring to North and South America.
"America" in Russian is "Америка" pronounced as "ah-MYE-ree-kah".
Amerique ("ah-mare-eek") but if you're talking about America as in the United States of America, you would say "Les Etats-Unis" (literally translated to "the states united") which is pronouced "layz ay-tahz you-nee"
Congress of the United States of America, or you could say the legislative branch.
You say that because you are making a promise the the flag that you are united to the laws, and you are saying you belong to the united states of America
