American universities don't have preparatory courses like those in Britain, Australia and other countries.

For students with language scores (TOEFL, IELTS, etc.). ) If they meet the requirements, they can take degree courses directly in the United States.

For foreign students whose language scores can't meet the requirements of undergraduate degree courses, or who have no language scores, many American universities now offer language courses (also called ESL courses) for 2 to 12 months according to their language level.

After the end of the language course, students can directly enter the undergraduate study as long as they pass the language test in the university. This is what we often call "conditional admission" for undergraduate students-language courses and undergraduate students are admitted at the same time.

It is very safe to go to the undergraduate course after completing the language course in the university. Generally speaking, in some countries, it will not happen that you can't enter the university after finishing the preparatory course.
