Hi Ranjeet,
TOEFL or IELTS are part of the admission requirements. Top universities like Harvard, etc. do not require these scores as the applicants themselves are brilliant and do not require additional tests to prove their brilliance. I hope you got my point. Universities may also waive of these requirements depending on the candidate's profile and communication skills. I will recommend you to communicate with the universities before you apply.
