How can a foreigner adapt while studying in Korea?

For foreigners considering studying in Korea, the biggest concerns are academic and adapting to life. Many are curious about what university life is like in Korea and whether there are support programs for international students. Important questions also include how to cope with a lack of Korean language skills and the actual level of academic pressure in Korea. University life in Korea is quite active, with various club activities and exchange programs. However, international students may face difficulties in initial adaptation due to language barriers. Accordingly, many universities offer Korean language classes and mentoring programs for international students. Living expenses are also a factor to consider, as costs can vary depending on the type of accommodation. In this situation, what preparations are necessary to adapt well to university life? Is there sufficient support for international students? I would like to hear the opinions of those with experience. Please share your experiences and advice.
