Living abroad as an au pair or exchange student often raises the question: Why would a host family want a complete stranger living in their home?

Well, the truth is—it’s not just about free help with the kids or practicing English.

There’s so much more to it. Host families open their doors (and hearts!) for reasons that might surprise you.

If you’ve ever wondered what makes you such an appealing guest, here are eight heartwarming and sometimes unexpected reasons host families are excited to welcome someone like you into their lives.

1. They Crave Cultural Exchange

You might think you’re the only one who’s curious about a new culture, but host families are just as eager to learn about yours. Hosting an international guest gives them the chance to explore the world without ever leaving their home.

From teaching them how to cook your favorite dish to introducing them to local music or slang, you’ll find that many families are genuinely fascinated by cultural differences. It’s a mutual exchange that goes far beyond the typical tourist experience, and families often feel like they’ve gained not just an au pair, but a passport to a new perspective.

2. You Bring a Fresh Perspective to Family Life

Living with the same people in the same house day after day can create a kind of bubble. You, as an outsider coming in, shake things up in the best way possible. You introduce new ideas, different ways of doing things, and a sense of curiosity that families often find refreshing.

3. It’s a Way for Their Kids to Learn Language and Empathy

For many families, especially those with young children, one of the biggest motivations is giving their kids the gift of a second language or a global mindset. Having someone speak a foreign language around the house exposes kids to new sounds and phrases in a way that no app or textbook can replicate.

But it’s not just about vocabulary—your presence helps kids learn empathy, adaptability, and social skills. They get to practice being patient, asking questions, and being kind to someone from a different background.

Parents often say their kids become more open-minded and respectful simply by having an international guest at home.

4. You Become Part of the Family

It’s easy to think of the host-guest dynamic as formal, but in many cases, host families truly want you to feel like one of their own. They invite you to family dinners, bring you on trips, and celebrate holidays with you. The bond that forms often goes beyond a temporary arrangement—it turns into something personal and lasting.

You may start off feeling like “the au pair” or “the exchange student,” but before long, you’re joking with the kids, having deep conversations with the parents, and getting tagged in family group chats. Some hosts even stay in touch with their former au pairs for years, meeting up for reunions or traveling across the world to visit them.

5. Hosting Is a Life-Enriching Experience for Parents, Too

For parents, life often revolves around work, chores, and parenting. Hosting someone from another country is a way to break that routine and add a spark to everyday life. Conversations with you bring in new energy, fresh stories, and thoughtful insights that many adults truly appreciate.

Some parents have always dreamed of traveling or living abroad but haven’t had the chance. Welcoming you into their home becomes a way to live that dream vicariously. You may find yourselves discussing politics, pop culture, and even swapping book or movie recommendations.

It’s not unusual for hosts to say they’ve learned as much from their au pair as their au pair learned from them.

6. They Want to Be Global Citizens

More and more families today are aware of the interconnectedness of our world. They want their children—and themselves—to grow up understanding and appreciating global diversity. Hosting someone like you is a concrete step toward being a global citizen.

By sharing their home with someone from a different background, families show their kids that the world is full of different ways of living and being. It’s a powerful lesson in inclusion, tolerance, and curiosity. For many, it’s also a statement of values—a way to live out their beliefs about community and human connection.

7. You Help Lighten the Load (And That’s Okay!)

Let’s be real—yes, having an au pair or guest does help families with day-to-day logistics. Whether it’s an extra pair of hands during the morning chaos, a buddy for homework time, or someone to watch the baby while mom takes a shower, your help matters.

And that’s not a bad thing! Most hosts aren’t looking for a nanny or servant. They’re looking for a helper who becomes part of their team—someone they can rely on during the week and laugh with on weekends. Your role brings real relief to their lives, and in return, they offer you a safe, supportive environment where you can grow.

8. They Love the Idea of Building Lifelong Connections

Some host families start hosting with no idea how meaningful the experience will become. What begins as a short-term arrangement often blossoms into a long-term relationship. They see you grow, adapt, and succeed—and that makes them feel proud and connected to your journey.

Many hosts say they feel like they’ve gained a son or daughter abroad. Birthdays are remembered, holiday cards are sent, and sometimes, even more au pairs follow as younger siblings hear stories and decide to try it, too. The connection can last far beyond the initial stay, turning into a lifelong friendship across borders.
