Ans: Students belonging to the OCI (overseas citizens of India) category are not entirely restricted from taking part in the National Standard Examination in Astronomy or the NSEA. This means that they are allowed to participate in the initial stage of the International Astronomy Olympiad Program followed by the subsequent stages of the exam as well.  But there has been a recent ruling by the Madras High Court which produced a verdict under which it was stated that even though the students belonging to the OCI category can participate in NSEA, they cannot go on to represent the country in the Internation olympiad program.
