Most hiring advice treats English like a binary, you either have it or you don’t.
That’s useless.
A backend developer who barely speaks but writes crystal-clear bug reports is infinitely more valuable than someone with a perfect accent who can’t document their work.
A customer support rep needs completely different English skills than a data analyst.
Here’s the reality most companies figure out after their first few hires:
For internal operations, data work, and technical roles where communication is mostly written, strong reading comprehension and clear writing matter more than speaking.
For roles involving regular client calls, team meetings, or cross-functional work, you need comfortable speaking and good listening across multiple accents. Not perfect, just comfortable.
For client-facing roles, sales, strategy, or leadership positions, near-fluent English becomes non-negotiable. You need someone who catches subtext, uses idioms naturally, and can “read the room” when a client is unhappy but too polite to say it directly. Strong C1 or higher.
Testing English the right way
Don’t just ask “do you speak English?”
Run an async written task. Email response, Slack summary, PR description. Then add a short video or voice note explaining a past project.
Then do a live call focused on: explaining technical decisions, handling misunderstandings, and giving pushback on ideas.
You’ll catch the people who write beautifully but freeze on calls. You’ll catch the people who sound great but can’t document anything.
Both matter. Match the test to what the role actually requires.
Where English proficiency actually varies across Latin America
Argentina consistently leads the region in English proficiency. Buenos Aires especially. You’ll find near-fluent English in senior dev, PM, design, and client-facing roles without much trouble.
Uruguay follows close behind. Montevideo has strong bilingual talent, especially for full-stack, DevOps, and UX roles with cross-border exposure.
Colombia sits in the moderate band overall, but Medellín has become a tech hub with strong backend, data engineering, and DevOps talent.
The English is good enough for technical work; you’ll need to invest more in communication norms for stakeholder-heavy roles.
Mexico City and Guadalajara have moderate and rising English proficiency. Great for support, frontend, and product ops roles.
Costa Rica punches above its weight for English, especially in customer service and support roles.
Don’t just ask “which country?” Ask which city, which university pipeline, which industry background.
The accent question everyone dances around
Accents matter for phone-heavy customer support and sales roles. Not because the accent itself is a problem, but because some customers will complain the second they hear a non-American voice.
Support workers will tell you: some customers claim they “can’t understand” foreign accents, but suddenly follow instructions perfectly when they realize a technician won’t just be dispatched.
It’s often bias dressed up as comprehension issues.
But comprehension can be real too. A thick accent combined with fast speech and technical jargon creates actual friction.
When accent matters vs when it doesn’t
Accent matters: phone support lines, outbound sales, video-heavy client work, any role where Americans will judge “professionalism” by sound.
Accent doesn’t matter: code-heavy work, internal analytics, design, writing, async-dominant teams, back-office operations.
For phone roles, run short mock calls with typical customer scenarios. Check comprehension under stress. Angry caller, complex instructions, all of it.
Provide scripts and phrase banks tuned to your main market.
What Latin American workers need to do
If you’re reading this from Latin America, wondering what level of English you actually need: a solid B2 is good enough to start for many roles. Strong B2 to C1 opens most doors.
C1 or higher is what agencies and platforms often require for client-facing work.
But the level is only part of it.
Communication skills that matter more than vocabulary
Write clear, concise status updates and emails. Short. Bullet points. Explicit next steps.
Stop the long, formal emails. US clients want to know: what’s done, what’s blocked, what you need from them.
Practice running client calls: opening, aligning on agenda, summarizing decisions, confirming next steps verbally.
Get comfortable asking for clarification. “Just to confirm, you need X by Friday, correct?” is professional. Pretending you understood and then missing expectations kills trust.
Take recognized English tests. Include honest scores on your profiles. Record short video intros in English showing how you explain your work.
Make your time zone an asset
Show your overlap hours with US/UK/AU explicitly. Suggest meeting windows.
Be proactive around holidays. Share your country’s key holidays up front. Propose how you’ll cover work or hand off responsibilities.
Learn to say “no” or “I need more time” directly. Learn to bring up blockers early. This counters stereotypes some employers mention about passivity.
US business culture values directness more than you might be used to. It’s not rude to disagree or flag problems early. It’s expected.
The real threshold
English proficiency is a lever, not just a filter.
It unlocks better roles, smoother collaboration, and legally sound long-term relationships.
But it’s never just about the language.
It’s about whether someone can keep projects moving without misunderstandings.
Test for that. Hire for that. Build systems that teach that.
The English will follow.
