The hidden ways language barriers affect expat careers
For many internationals, moving abroad is driven by career ambition. A new country often represents exciting opportunities, professional growth and the chance to build a better life. But while many expats carefully prepare for the practical side of relocation, language barriers are often underestimated until daily life and work become more complicated than expected.
According to Michelle Knuth from Alpadia Language Schools, the impact of language on professional life goes far beyond simply being able to do your job. “You might think you can get away with only English,” she explains. “But then it turns out you cannot when it comes to going to the doctor, handling bureaucracy, or simply living daily life outside the office.”
Even when someone enjoys their role and works in an international company, the local language can still shape how connected, confident and integrated they feel.
The career impact people do not immediately see
In many international workplaces, English is the primary language. That can make it seem like learning the local language is optional. But Knuth says the reality is often more complex.
“It depends on the job,” she says. “If the office language is English, then the language barrier may not immediately feel like a problem. But outside work, not everyone speaks English, and that can make integration harder.”
Over time, that disconnect can quietly affect career progression as well.
“When it comes to higher positions, you often need to deal with different stakeholders,” Knuth explains. “People may connect differently with someone who speaks their own language fluently.”
She adds that, while language alone may not stop someone from progressing professionally, it can become a deciding factor when candidates are otherwise equally qualified.
“It could be a reason why they choose the colleague who speaks the language fluently over you.”
Why informal conversations matter
Professional integration is not only built during meetings and presentations. Some of the most important workplace moments happen informally: during coffee breaks, lunches or after-work drinks.
Knuth believes these relaxed situations are often where language learning improves the fastest. “You are more relaxed and not focused on performing perfectly,” she says. “You might try new phrases for the first time and realise where you still struggle or where you are already doing well.”
Those conversations also help internationals feel more included in workplace culture, especially in environments where colleagues naturally switch back to their native language socially.
“You might miss local jokes, news, memes or cultural references colleagues talk about in their mother tongue,” Knuth explains.
Over time, that can contribute to feelings of professional isolation, even inside international companies.
The confidence challenge of working in another language
One of the biggest hidden effects of language barriers is their influence on confidence at work. Knuth points out that even fluent English speakers can suddenly feel less expressive when working in another language.
“We are doing it right now,” she says during the interview. “We’re not speaking in our mother tongue. Sometimes you know exactly what you want to say in your own language, but you struggle to find the word in another one.”
For professionals who are less fluent, those moments can quickly create self-doubt. “If colleagues do not understand you, you may hesitate to ask questions because you are afraid it will take too long to explain yourself,” she says.
Many internationals also worry about sounding less intelligent or professional when speaking another language. According to Knuth, this fear is extremely common among learners. But she believes people are often far more understanding than learners assume.
“Most people are actually very happy to see that you are trying to learn the language,” she says. “If they switch to English, it usually comes from wanting to help, not because they are judging you.”
Why immersion changes everything
At Alpadia, immersion is a core part of language learning. Rather than limiting learning to textbooks or classroom exercises, students are encouraged to surround themselves with the language daily.
“If you really want to use a language confidently, you have to confront yourself with it,” Knuth says. That means hearing the language on public transport, in cafés, during social events, through music, films and everyday conversations. While that can feel overwhelming initially, she says it dramatically accelerates progress.
“You might make more progress in a few weeks of immersion than in two years of only learning through writing or sitting behind a laptop.”
For career-focused learners, that immersion also helps build cultural understanding and workplace confidence much faster than passive learning alone.
More than a language course
Knuth believes one of the biggest misconceptions about language learning abroad is that it is only about grammar or vocabulary.
“A language trip is not only a language trip to learn a language,” she says. “It is so much more.”
Alpadia offers immersive language programmes designed to help students build confidence in real-life situations, whether for professional growth, university preparation or personal integration abroad.
And for professionals feeling hesitant about learning later in life or worried about making mistakes, Knuth’s advice is simple: “Step out of your comfort zone. Very quickly, it becomes your new comfort zone.”
