Yiddish Language Immersion Classes

There are a number of different Yiddish language immersion options for people who have the time/money and who want to improve their Yiddish-language skills in a relatively short time-frame:

1. Yiddish Book Center program in Florida (January 2016: 1 week)
2. Yiddish Book Center program in Amherst (March 2016: 1 week)
3. Yiddish Book Center Summer Program (Summer 2016: 7 weeks)
4. YIVO Uriel Weinreich Summer Program (Summer 2016: ~1 month)
5. Tel Aviv University Summer Program (Summer 2016: ~1 month)
6. Vilnius Yiddish Institute Summer Program (Summer 2016: ~1 month)

There are also summer programs at some of the universities, local classes at Jewish community centres and synagogues, as well as the classroom/online courses provided by the Workmen's Circle; however, the above 6 are the only Yiddish language immersion-like courses that I know about that are happening in the next 10 months. Anyone know of other programs that aren't mentioned here?
