תרגום - טורקית-אנגלית - türkiyeye hiç geldin mi

The word "in" is incorrect, and should be replaced by "to"

The negative can be used in such a phrase, but it would be better formulated in a positve form, by using "ever" instead of "never"

The phrase would then be:

"Have you ever been to turkey?" (sounds interrogative)

If not it should read:

"Have you never been to Turkey" (sounds incredulous or ironic)

in French, as Tantine said, it would be
1 : "es-tu déjà venu(e) en Turquie"
2 : "N'es-tu jamais venu(e) en Turquie"

Are you sure that never been is correct?

I'd say that what would sound better is:

"Haven't you ever been to Turkey?"

Hmm, I'm thinking, it actually means 'have you ever been to turkey?', it's a sort of fixed expression..
