As a soccer enthusiast, I've always been curious about how the different leagues and organizations connect. Recently, I've been wondering if Major League Soccer (MLS) is a part of FIFA. After doing some research, I found out that MLS is indeed affiliated with FIFA, as it operates under the United States Soccer Federation, which is a FIFA member. This affiliation ensures that MLS follows FIFA's rules and regulations, and it allows the league to participate in international competitions. It's fascinating to see how various soccer organizations around the world come together under the FIFA umbrella.
