I am USA citizen. My passport ran out of pages. So I went to USA embassy in HCMC and got new passport. They put 2 holes in my old passport to "void" it. I want to leave Vietnam soon. I went to immigration office in Nha Trang today (twice) and they told me that I could not leave with my current passport situation. I was sent to 2 different tourist agencies and neither of them can transfer my visa to my new passport. I think that one of them said that they can get me an extension but I have a month left on my old visa and I do not need to extend. I just want to leave. Does anyone know of a local tourist agent that can transfer my visa (stamp) to my new passport?
