If I go to some Arab country like Iran or Saudi Arab, will they put me in jail for doing anything that is not allowed in their religion (not necessarily against)?
I read in news some people got prosecuted for religious based crimes.
If you visit a foreign country you are subject to their laws, and you may not be protected under any United States rights. You may even be denied to see a member from the local American embassy in some places. Why would you wish to visit any of the countries you listed anyway?
