In the US, there are three different admission intakes. The intakes are spring, summer, and fall, with a massive pool of applicants at each one of them. Students can choose any intake depending on their preferences. The spring intake session commences in the month of January and concludes in April. The summer intake session commences in the month of May and concludes in August. The fall intake session commences in the month of September and concludes in December. So, one can comfortably say that all-around admission sessions are going on throughout the year.
Students can take the liberty of choosing an intake session depending on the time of the completion of their studies in India, also on the availability of test dates (for GRE, TOEFL, IELTS, etc.), time taken for loan processing, getting the visa, and other important factors.
