After completing your 12th grade, you can apply for undergraduate programs abroad by choosing your preferred course and country. The process usually includes selecting universities, meeting eligibility requirements, preparing for language proficiency tests like IELTS or TOEFL, and submitting academic transcripts and supporting documents. Once you receive an offer letter, you can proceed with visa application, financial planning, and travel arrangements. Consulting an education expert or agency can make the entire process smoother and ensure you choose the right path for your goals.
