I recently obtained a new passport, the old one having the information of my guardian as I was under age , When I left my country after getting it, I used the new passport as it is the current one, but I entered Turkey using the old passport, as I have a permit card that has been registered under it. Could this be a problem? What can I do? I must go and let them know of the change. I have been to the embassy of my country, and they gave me a supporting document informing of the change. However, would the stamp in my new passport showing I left my country be a problem, as the entry stamp from Turkey is in my old passport?
