FAQ
Q: When will Language X be added?
A: Short answer we don't know. Duolingo relies on volunteers to build new courses, therefore your desired language will only be added when there are enough capable volunteers to build the course. Duolingo has typically followed a pattern of giving priority to new English courses first. Once that course is complete and tested, the same team can then begin reversing the course, this is the only indication we have of when your course may be added.

Q: How can you know when some reverse courses will be added?
A: They are predictions, we know that Duolingo added the new courses for English speakers after their counter reverse courses had been in beta for 60-100 days, so its reasonable to assume a similar pattern will follow in future. With that said all dates and times on this page are independent of Duolingo, please treat them as such. Never quote dates and times from this page to complain to the Duolingo team or contributors.

Q: How long does a course take to complete?
A: Typically it takes 3-6 months for a course to make its way into beta, it all depends on the amount of free time the team can devote to the new course.

Q: Can I help?
A: If you bilingual and able to write at the level of a native speaker of 2 or more languages you may be able to contribute, follow link to submit an application to the Duolingo team. Otherwise you can help by simply learning a language in beta and submitting any errors or bugs you encounter.
