When have you been in Tehran?s

Are you sure?

Some believe that "when" refers to a "specific time"

while we use "Present Perfect" to talk about a "non-specific time".

Answer 2

have you ever been to Tehran?

Answer 3

when had you been in tehran?

Comments

Hi

This is past perfect, not present perfect. the "had" has to be "have".

Answer 4

These are the example I could come up with:

Since when have you ever been to New York? 

When, if ever, have you been to new york?

when, ever, have you been to new york? (with something like an angry tone maybe,)
