Hi, I am traveling on the Vietnam, Cambodia, Thailand trip in October. I started the e-visa process. Pictures uploaded and I got a green check, entered all the required information, but when I got to the security Captcha, it just goes into a loop. Trying to hit NEXT, displays "Notification Captcha Invalid". I have tried clearing cache, rebooting, updating Chrome, using my phone, and finally, trying using Safari with a clean cache, etc. Nothing works. Any ideas? My next step may be to use VisaCentral and pay to have someone do it for me.
