Washington, DC

Imagine a city that feels like a park but has museums, concerts, monuments, festivals and great restaurants. You have heard about Washington, DC, the capital of the United States, for a long time. Aren't you curious to see what it is really like? This city was made for students and tourists. The museums are free, the concerts are numerous, the people are friendly and helpful and the public transportation is very convenient. Come for a month to visit or come for a few years to improve your English and then continue on to study at a famous US university or college.

Study at one of our schools in the Washington D.C. area. One is located right in the heart of the US capital near:

  • Subway and bus stops
  • Free museums, galleries, and zoo
  • Top U.S. universities
  • The White House
  • The Capitol

The second school is located in Gaithersburg, Maryland, a beautiful suburb just 15 miles outside of the city.
