Q. Is there a point for him(a Israeli resident who temporarily travels to Chutz Laaretz) to say Izkor as it is not Yom Tov for him or should he say it by himself on the first day?

A. Betzel Hacochmo (4: 109) rules that an Israeli resident who temporarily travels to Chutz Laaretz should recite Izkor on the first day by himself.

Yom Tov Sheni Kehilchoso (13; 4) mentions that he was advised that Horav Moshe Feinstein’s Zt”l opinion was not to say Izkor at all. However, Horav Shlomo Zalman Ouerbach Zt”l wondered why not and ruled that it should be recited on the first day and preferably also on the second day, together with the rest of the community.

Horav Shlomo Miller’s Shlit”a opinion is to join everyone else and say Izkor on the second day.
