The first requirement is to hold an undergraduate degree related to the chosen MS field and to have completed at least 16 years of education. If you meet these requirements, you can start taking the standardised tests that are required for most MS-level programs in the USA, such as: Graduate Management Admission Test (GMAT), in which most institutions require you to have a minimum of about 740. This is recommended for business and management programs.  Graduate Record Examinations (GRE), in which a minimum of around 290 - 330 is required. English Language proficiency tests, such as the International English Language Testing System (IELTS) or Test of English as a Foreign Language (TOEFL). Other tests, such as PTE or Duolingo, are also accepted in some universities.  In most institutions, you require a minimum of 90 - 100 in TOEFL or 6.5 and above in IELTS to be eligible.
