good luck finding a JW in Muslim countries
Ditto. JWs are under severe restrictions, even if not exactly under ban, in Muslim countries. There is likely not an open meeting to attend. In particular JWs, (I believe this applies to all non-Muslim religions) are not allowed to proselytize, only preach to other non-Muslims with the intent to convert.
A few years ago I was shocked to learn that JW need-greaters were going into Morocco under assumed names, with no support from any JW branch. They were out there totally on their own, taking such risk. Really a bad idea.
