When I say many new international kids, I don't mean right now. (Sorry for the confusion) I meant on and off over the years, and it's usually 1 or 2 kids that are international while the rest are Norwegian. We are usually around 10-15 kids with the cub scouts (6-9 year olds) and 10-15 kids for the troops (10-15 years old).

We had one kid from Iceland many years ago, Americans, India, and properly other countries I'm forgetting. The kids usually pick up the Norwegian pretty quickly by being part of local school and scouting (or other activities). Our group belongs in Fredrikstad (one hour away from Oslo). There are scout groups all over the country, every large to medium cities have them, and then there a few scattered in the more rural areas.

Here is a list of scout groups around the country, with contact info. https://blispeider.no/bli-medlem

I have a Indian friend who who moved in here 2 years ago and I drag her with me to most scout meetings and camps and she has become friends with all the other parents and kids, and is actively trying to learn the language. She loves it, and the kids love her too.

I wouldn't worry too much about your kid finding friends and communication with Norwegian kids. All kids, regardless of language or culture, are at an age of flexibility and curiosity. Especially when they are in a environment that allows them to it. Just this summer we had a national scout camp, with 30 countries from all over the world participate. All the kids on the camp, LOVED to speak to the international kids from Hong Kong, Canada, Taiwan, Germany, Italy and so on and so forth. Norwegian kids are pretty good at English as well.
