An Economically Weaker Sections (EWS) certificate typically doesn't play a significant role in securing admission to overseas universities. International universities primarily assess applicants based on academic qualifications, standardized test scores, letters of recommendation, personal statements, and other relevant factors. While financial documentation may be necessary to obtain a student visa, EWS certificates are specific to India and may not be recognized or considered by foreign institutions. Scholarships and financial aid may be available separately, but they are generally based on merit, need, or specific criteria set by the universities themselves.
