As a us organization you can choose between different MS cloud tiers. I know about 3, the basic tier for private customers, tier4 for large corporations and tier 5 for us gov and military organizations. My guess would be that it has something to do with which 3 letter agency can access your cloud data.
Before you get a career, live and work in another country or travel on a budget for a year. See other places, meet new people, learn lots of new things and get out of your comfort zone. Some people just walk or bike across a continent with a tent.
You won’t be able to do it later in life when you have a job, family and commitments.
