Dear Sir or Madam,
I am writing this letter to say that summer language courses abroad are a fantastic opportunity to improve the language level. It is always popular among students all over the world to go to the summer courses abroad to study and develop their knowledge. I think you can also improve your English knowledge while traveling, experiencing other cultures and making new friends. It is important to be motivated. However, while being abroad you can face cross-cultural barriers, feel homesickness or very alone. But you should focus on what is the most important for you and enjoy the time.
Best wishes,
