Dear Michael,
Thank you for your inquiry to the (U) Vebbe Rebbe and for your patience.
In response to your question:
The opinion of the OU is that the ruling of Reb Moshe Feinstein applies to
European countries, as well. It would not however apply to Third World
countries.
Good Shabbos,, The (U) Vebbe Rebbi
