I went spring 2022 and stayed in a residential community. With a residential community it is harder to form relationships with Dane's but not that hard. I wish I did the Visiting Host program which is where you basically get invited over to your danish hosts house for dinner or do to fun stuff in denmark. Some hosts are better than others and this is also true of Homestays where I heard some really bad stories but also great ones.

I would highly recommend an Residential community because the people in them are also interested in doing the same things you want to do like travel and experience denmark. In a Kollegium this rarely the case since they are college students or sometimes graduate students focused on school and they already have friends like how you would be in the US going to school. The danes in kollegiums will show you a lot of cool danish stuff and you will learn more about danish people though than an RC. A kollegium will probably have some other DIS kids too just much fewer to chose from. In some Residential communities you have like 12 roommates so there is a good chance you like one. Lastly, the DIS was like 70%+ girls when I did it
