Vietnam visa for United States citizen

[alex8912]

I am looking for very recent info regarding getting a visa for Vietnam for a visit from Feb 5 to 10. I will be only traveling to Nha Trang and entering via Nha Trangs Cam Ranh  Intl airport. There are many incorrect and confusing info on my google search but what I believe is that since Feb 1, 2017 Americans can get an e visa on line for $25 and that's it. But when I look at ports of entry for this Nha Trang seaport is listed but not Airport. Does anyone know if this is true? I have my air ticket and hotel booked and just wanted to know if anyone with a USA passport has recently entered at Nha Trang airport and what did you do for a visa? I am in Bangkok until I leave for Malaysia and Vietnam. 

Thank you for any info.
