this sentence is not really a question right? this sentence is use when u want to display(anyway like that) ur feeling right?

So "itsu" not use for feeling or mind, it's use for physical question only
as this : - By japanese, they not use S and V clearly- and they not use "come- kimasu (kuru) " in the question ask to other people who far from them.- japanese use "going - ikimasu" instead of .

so i think u should refer below situations
+) "toki" use as logical question not clearly if u want to ask for onethings only for mind .
(anata) kimi no hou ni iku toki = when I come to you (continue .... not really a question)

+) itsu uses as physical question as :
itsu watashi(boku) no ie ni ikimasu ka? = when will you come to my house?

Note : watashi = boku = I
anata = kimi (use for girl only -not for a man or other)= you

@lacagalbu:
Sorry , I'm learning English now (also, japanese too) . Therefore ,I'm not sure that u could understand all what i said. Might be it's not clearly and easy to understand. But I'm glad to help u in nihongo (japansese) not english :D. :p :p

Don't worry, you're english is understandable :)
However I don't understand what u mean by "people who far from them", u mean that ikimasu is more formal than kimasu?

Ah, "when i come to you?" it's a "physical" question (it should be "when do I come to you?") but, no matter, I think i've understood that
