Ah thanks, I appreciate it. I'm thinking specifically of Soeul and surrounding area.
(1) I'm wondering if there is any sort of Jewish community. I would invite my in-laws to come, they and my son are Jewish. Is there a Jewish temple somewhere? Are Jews well received?
(2) Any idea where/if there are elementary schools that teach in English?
(3) How good/safe is the community around Korea University? Any chance they'd understand English around there (I figure it will take me some time to learn Korean). Or, how easy/reliable is travel to and from KU by subway?
I appreciate it, and if I think of more, I'll be back.
I don't know of a Jewish community here. There is no synagogue in the city, but apparently there is one on the US base at Yongsan. This is close to the city centre but access is, of course, restricted, although accompanied visitors are permitted, as are holders of other military or veterans' ID.

The only elementary schools teaching in English are the international ones, including the US school on Yongsan base.
The community is generally very safe wherever you are in Korea. Violent crime is very, very low here. (In part, this may stem from the absence of a concept of "self-defence" in that where a fight occurs, the victim is the most injured. Self-defence is no legal defence.)
The subway system is excellent - if crowded on some lines at peak times - and cheap. I think it is the third largest system by ridership in the world and about 5th by miles.
Many Seoulites speak some English, especially the younger ones. Korean is one of the hardest languages for an English speaker to learn. I speak 4 languages but have been strruggling for 4 years to get a grip on Korean and am still barely at "low-intermediate". That said, they use an alphabet of 24 characters and that can be learnt in a couple of hours: this will at least help with reading direction signs, menus and stuff, even if you do not immediately know what the word means.
Letters are groupled into syllables. For example the word "Han" - Korea - is composed of 3 letters of Roman characters and 3 characters of Korean (Hangeul) characters:-
H a n
ㅎㅏ ㄴ
In the Korean word, these three characters are written together to form
한
(I hope you can see the characters - if not, try mouse right click, encoding, Korean)
Overall, a good place to be.
