FAQs

  • A supporters group is a community of fans who come together to cheer on their team in an organized, energetic, and engaged way.

    Not only do they create an electric atmosphere at games with chants, flags, songs, and coordinated cheering but supporters groups often do more than just attend matches—they engage in social events, charity work, and help promote the team and the sport within their local communities.

  • Short answer: Nope!

    Longer answer: NWSL Boston ISA is an independent, fan-run 501c(7) non-profit association.

    We are not affiliated with or controlled by the Boston Legacy FC franchise.

    While we certainly root for the team, we operate separately - making our own decisions and working solely to promote the best interests of our members.

  • 2025 Memberships are only open to adults (18+) who live in the United States. We are working hard to open this up in the future.

  • Memberships are available to purchase here.

    We do charge an annual membership fee. This fee funds group activities, tifo creation (those big banners you see at some games), start-up expenses, and will help to offset the cost of organizing events.

    We are an all volunteer-run 501c7 non profit organization, registered in the Commonwealth of Massachusetts.

  • This first year is all about building our community through meet-ups and other social events.

    The benefits and perks are growing as we grow, and we will start to keep a clear list on our website and communicate new perks, partners, and other benefits through our newsletter.

    The biggest benefit to being a member right now is to be part of building this wonderful community from the ground up!

  • We welcome fans of all levels—whether you're a lifelong soccer supporter or just learning about the team.

    • Not sure how the offside rule works?
      We are happy to explain it.

    • Worried a 3-back system might be risky against a team like Gotham?
      We understand your concern.

    Boston ISA is for every kind of fan, and we can't wait to meet you!

  • We are very excited about a revitalized White Stadium, and are thrilled to see the city has signed a 10-year lease agreement with the team, but truthfully, we know about as much as you do about the timeline of the renovations.

    If you would like to learn more, or get involved in the process, a great place to start is the city’s project page.
