Besides Chabad, which hassidic dynasty has a french or english speaking outreach (kirouv) program ?
I know Belz has one, but I cannot find more information about it online. I also heard that Satmar has one for french people but I am not sure.
Several Breslov (aka Breslev) groups are active in kiruv in the US. Breslov is the one branch of chassidus that never had a dynasty. Rebbe Nachman of Breslov did not believe in hereditary dynasties of rebbes. Instead, there has been a small group of Breslov gedolim in each generation.
One particularly active and prolific Breslov kiruv group is run by Israeli Rabbi Shalom Arush, and his charismatic English-speaking spokesperson Rabbi Lazer Brody. Their organization runs the website Breslev Israel (http://www.breslev.co.il), which is translated into several languages, including French and English, and a ba'al teshuvah-oriented yeshivah in Yerushalayim, Chut Shel Chessed. They have published numerous books and CDs, and Rabbi Brody frequently goes on speaking tours around Israel and in the US.
Rabbi Avraham ben Yaakov runs http://www.azamra.org, which provides translations of many Breslov works, including original texts by Rabbe Nachman, as well as his own books.
Rabbi Dovid Sears (who has also written several interesting books) runs a Breslov outreach organization called the Breslov Center (http://breslovcenter.blogspot.com/).
