"미국에 가기 전에 영어를 배우십시오."
Translation:Learn English before going to America.
Just want to say that the US does not have an official national language. Most of us speak English, but it's not at all a requirement for getting around. Many of our people, and most of our signs, are multilingual. If you travel through rural areas, the cell phone reception is unreliable, so you'll want to have some emergency phrases prepared in English and Spanish. For the most part though, especially in the big cities, you'll be perfectly fine with basic travel phrases and an understanding of our currency. (Oh, and sorry about the imperial measuring system. We don't like it either.)
Most signs are in one language in most places. There are areas with multilingual signs, but most are not multilingual, especially most traffic signs.
And we like imperial. There is no practical difference between metric and standard units besides converting in school physics class and measuring tiny/huge things.
We are fine using either or. No one will complain when given a metric tape measure nor a standard unit tape measure.
Only euro snob acts like using standard units is a crime against science.
