Does Duolingo offer internships?
This isn't a very good discussion topic, but as someone who loves languages a lot, and studies it right now in college, I'd love to participate with a program like this that offers the ability to teach people different languages in different ways. I plan on studying linguistics in grad school, but that's two year from now.
Could I work for Duolingo as an intern?
The internships are in very specific areas though, not just a general language internship. And they require technical background. Currently software (BS/MS pending) or product design (MS/PhD pending) internships are available.

There are no scholarships at this time (Dec 11, 2017)
It's on the coding/programming side.
Your best bet is to look for a local outreach/government programs for immigrants, there are everywhere even in the smallest rural cities. I know I seen one in the Mason area when I did some work there last year. Don't remember the exact location, was only in the area a few weeks. I'm sure Cincinnati/Dayton area has a ton.
