When do you think I should come?
I wonder if it is common for native speakers to say "When do you think?".
Yes, it's a common construction. It might help to imagine it like this:
When, in your opinion, should I come?
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
I am relieved that I am not into those spider's-webby diagrams. People who like them would probably have fun with When do you think I should come?
I think that the absence of pauses in speech and of commas in writing make it slightly different in meaning from When should I come, do you think?
Yes, I think you're right. Perhaps I should have suggested imagining it as:
At what time do/would you consider it a good idea for me to arrive?
Not, of course, that we would ever actually say that!
Health Warning: Do not read this, learners. It could be harmful to your mental health.
As a further complicater, your sentence above could perhaps be interpreted as, "You don't consider the idea of my arriving (at any time) to be a good idea. At what time would you consider this?"
