If you are attending in any US university u either need Toelf or Ielts.If u are International students and u don't have toefl or ielts they will put u in ESL which is very lenghty course . It takes around 2 yrs to finish ESL thanafter u will be eligible to enroll in regular class. So, brother If u are planning to come make sure u have either Toelf or Ielts otherwise US ma ayera dukha paulau. Ani kun university ho timilai I-20 Issue gareko?
TOEFL OR IELTS are MANDATORY otherwise they will put in ESL.

I'm assuming that section 6 of your I-20 looks like this:
_{This school requires English proficiency.
The student has the required English proficiency.} 

This means you already have Eng language (TOEFL or IELTS or other) skills required  for the admission in your school. If it clearly says that you have the required Eng language proficeincy, why would they put you in ESL classes. I don't really understand. 

Thanx ......... Section 6 states same ........................
